"Lone Wolf" Terrorists

Summary: Individuals acting alone posed one of the most difficult challenges for law enforcement authorities charged with combating terrorism. Long before the attacks of September 11, 2001, the United States violent actions by "lone wolf" terrorists used some of the same terror tactics associated with groups like Al Qaeda. In some cases, these individuals expressed an interest in joining foreign groups engaged in organized jihad. In other cases, their motives appeared to be entirely personal, such as grievances with the US Internal Revenue Service. Attacks carried out by lone wolf terrorists included single assaults and strings of attacks. 

While terrorist tactics have long been used by groups against the state, they have also been used by individuals seemingly unaffiliated with organizations. So-called "lone wolf" terrorists posed a particular challenge to law enforcement officials since they acted with no collaboration whatsoever, thereby thwarting traditional government intelligence efforts. Dangerous weapons such as bombs were constructed from everyday materials like fertilizer whose purchase raised no red flags. 

In some cases, lone wolves are captured only after they publicized their grievances after repeated attacks or when they used the media to threaten future attacks. Sometimes suspects were captured by chance—caught on a security camera or noticed by a passerby. Still, in other cases, lone wolves became suspects by expressing their desire to participate in Islamic jihad or to join larger groups. Such expressions have been discovered on Internet chat groups or in private notebooks examined by authorities. 

Motivations of lone wolf terrorists were usually expressed in negatives—killing an individual leader, harming a company, attacking a symbol. Lone wolves rarely expressed positive goals, such as establishing a government or a new social system. 

Combating Lone Wolf Terrorism

In 2004, Congress passed the Intelligence Reform and Terrorism Prevention Act with a provision specifically aimed at lone wolf terrorists. This defined lone wolf terrorists as those who acted in sympathy with the aims of an international terrorist group but not on its behalf, such as terrorists whose link to an international terrorist group could not be demonstrated. The legislation modified the earlier Foreign Intelligence Surveillance Act (FISA) as it allowed government officials to target lone wolf terrorists without showing them to be members of any group or to be agents of a group or foreign power. Previously, the National Security Agency prevented domestic electronic wiretaps on individuals due to concerns from civil liberties groups regarding innocent citizens being targeted due to benign actions like taking part in demonstrations. 

Examples of Lone Wolf Terrorists

The following table lists, in chronological order, attacks by "lone wolves" in the United States; details on selected cases are below. 

Finton, Michael. A former convict who converted to Islam while in prison. He was arrested in August 2007 for violating his parole. Police perused a notebook in which Finton had written that he was interested in joining an Islamic jihad outside the United States. Starting in January 2009, over the course of nine months, an FBI informant and an undercover agent worked to "gain control" of this impulse, in the words of the affidavit against Finton. Finton was arrested in Springfield, Illinois, on September 23, 2009, after he had parked a car he thought was packed with explosives near the federal office building in Springfield and had dialed a cell phone he thought was going to ignite the explosives. Finton never made contact with an external group, and the fake explosives and cell phone used in his alleged plot were both provided by the FBI. Finton was formally charged with attempting to detonate a weapon of mass destruction and attempting to murder federal officers or employees (i.e., workers inside the federal building). (See separate Background Information Summary in this database.) 

Furrow, Buford O'Neal, Jr. On August 10, 1999, Furrow opened fire on a daycare center at the North Valley Jewish Community Center in Los Angeles, injuring three children, a counselor, and a receptionist. Later the same day, Furrow shot and killed a postal service carrier who was a Filipino American. A US attorney later said Furrow admitted killing the postal worker because he was "non-white and worked for the federal government." Furrow was reported to have been taking medication for psychosis at the time of the shootings. After the shootings, he fled to Las Vegas, NV, by taxi. He surrendered the next day and confessed to the shootings. In October 1998, Furrow tried to commit himself to a psychiatric hospital in Kirkland, WA, telling authorities: "I am a white separatist. I've been having suicidal and homicidal thoughts for some time now. Sometimes I feel like I could just lose it and kill people. I also feel like I could kill myself." In the hospital he pulled a knife on a nurse, for which he served five months in jail. The Los Angeles shootings occurred about three months after he was released and put on probation. 

Hadayet, Hesham Mohamed. A legal immigrant to the United States from Egypt. On July 4, 2002, he got into line at the counter of El Al Israel Airlines at the Los Angeles airport armed with two handguns. He opened fire, killed two people, and wounded two others before Israeli security agents shot and killed him. The FBI never provided a clear motive for the attack, although a friend said Hadayet often expressed hatred of Israelis "because they're destroying the Egyptian people." A subsequent investigation showed that Hadayet's limousine service was suffering financial difficulties and that he had lost his California chauffeur's license after letting his automobile insurance lapse. 

Ibrahim, Andrew Isa. Convicted in Britain in July 2009 on charges of plotting a suicide attack at a shopping mall in Bristol, England. Ibrahim was the son of a British mother and an Egyptian Coptic Christian father. Ibrahim had a troubled childhood, including multiple expulsions from school and a drug habit. He was described as having an "addictive personality" that drove him to use drugs, steroids, and computer games. He harbored a "bizarre foot fetish" before being attracted to extreme Islam. He was enthralled by sermons from extremist clerics and suicide bombers in Britain. He also showed signs of being alienated from British society, which he described to friends as a "dirty toilet." Police were alerted to his behavior by other Muslims, including someone who saw that Ibrahim had burned his hands while experimenting with explosives. Ibrahim was not thought to belong to any organized terrorist organization. 

Malike, Sayed Abdul. In April 2003, federal officials charged that Malike, a native Afghan and a New York City taxi driver, had tried to buy enough explosives from an undercover agent to "blow up a mountain." His motives, or even his plans, remain unknown. Malike revealed his thoughts when visiting a shop in Queens, New York, where he sought help with his computer in March of 2003. During the visit, he asked the store owner how to make a bomb; the owner later called the FBI. Later that month, Malike took a trip to Miami, during which he videotaped bridges and asked a tour boat captain about their infrastructure. The tour boat captain also called the FBI, who questioned Malike but released him. Back in New York, Malike returned to the computer store and confided to the owner (now a government informant) that he wanted to buy enough explosives to "blow up a mountain." Later, he met with an FBI undercover agent and tried to buy bulletproof vests, night-vision goggles, Valium pills, and a half-case of C-4 explosives. Malike's failure as a terrorist apparently stemmed from his ignorance of bomb-making techniques—the sort of knowledge that often motivates terrorists to work in groups. 

McVeigh, Timothy (Oklahoma City Bomber). Strictly speaking, McVeigh was not a "lone wolf;" a friend, Terry Nichols, was convicted of aiding him in planting a truck bomb outside the Alfred P. Murrah Federal Building in Oklahoma City on April 19, 1995, killing 168 people. But McVeigh fitted the overall pattern insofar as he belonged to no larger group, and his motive was apparently to gain revenge for the deaths of people killed in a federal raid near Waco, TX, on a group of religious dissidents called Branch Davidians. McVeigh, who had served in the US Army, apparently felt a strong sense of social alienation, especially after he flunked out of training for the Army's Special Forces. 

In a letter to a journalist while awaiting execution, McVeigh declared: "Foremost the bombing was a retaliatory strike; a counterattack for the cumulative raids (and subsequent violence and damage) that federal agents had participated in over the preceding years (including, but not limited to, Waco). From the formation of such units as the FBI's Hostage Rescue and other assault teams amongst federal agencies during the 80s, culminating in the Waco incident, federal actions grew increasingly militaristic and violent, to the point where at Waco, our government —like the Chinese—was deploying tanks against its own citizens. For all intents and purposes, federal agents had become soldiers (using military training, tactics, techniques, equipment, language, dress, organization and mindset) and they were escalating their behavior." 

McVeigh's attack was the deadliest terrorist attack in the United States prior to the September 11, 2001, Al Qaeda attacks on the World Trade Center and Pentagon. McVeigh was caught by happenstance—a highway patrolman pulled him over for driving without license plates and arrested him for driving with a pistol. McVeigh was convicted of setting the Oklahoma City bomb and was executed on June 11, 2001. 

Muhammad, Abdulhakim Mujahid. in June 2009, killed one soldier and wounded another when he opened fire at a recruiting center in Little Rock, Arkansas. A convert to Islam, Muhammad had traveled to Yemen, where he married, was imprisoned, and was deported for overstaying his visa. He was also interviewed by the FBI while imprisoned in Yemen. Family members said he was infuriated by American involvement in Iraq and Afghanistan. He eventually claimed to be a member of Al Qaeda in the Arabian Peninsula, based in Yemen. His case was overshadowed by the shooting at Fort Hood, Texas, also said to have been inspired or directed by the Al Qaeda in the Arabian Peninsula. 

Malvo, Lee Boyd. Accomplice to John Allen Muhammad (see below). Malvo, age seventeen at the time of a shooting spree in October 2002 that killed ten people, seemingly at random, was sentenced to life in prison. 

Muhammad, John Allen. For three weeks from October 2, 2002, a string of ten fatal shootings, seemingly at random (victims were shot while filling their cars with gasoline or while shopping), caused widespread unease in the area around Washington, DC. The crimes were eventually blamed on a pair of shootersJohn Allen Muhammad, a nine-year army veteran, including service in the Gulf War, and seventeen-year-old accomplice, Lee Boyd Malvo. The pair demanded ten million dollars in exchange for halting the shootings. Muhammad was described as a sympathizer of Al Qaeda who may have had personal problems. One report said he had planned to include his wife among his victims, hoping her death would be attributed to an unknown gunman rather than a case of domestic violence. Muhammad and his partner were arrested, sleeping at a highway rest stop. Muhammad was executed in November 2009. 

Rudolph, Eric Robert (Olympic Park Bomber). Rudolph planted a series of bombs across the United States that killed three people and hurt about 150. He declared he was acting against abortion, "the homosexual agenda," and what he perceived as government support for both. Rudolph's most notorious act occurred on July 27, 1996, in Atlanta's Centennial Olympic Park during the Summer Olympics. A bomb he set killed one person and injured 111. Rudolph later declared the Olympics were a celebration of "the ideals of global socialism" which he opposed. He said he also wanted to "confound, anger and embarrass the Washington government in the eyes of the world for its abominable sanctioning of abortion on demand." Rudolph later confessed to three other bombings: at an Atlanta abortion clinic (January 1997), a gay nightclub, also in Atlanta (February 1997), and an abortion clinic in Birmingham, AL, where one policeman was killed (January 29, 1997). Rudolph denied allegations he belonged to a White supremacist group called Christian Identity. Rudolph eluded arrest until May 31, 2003, having apparently survived in the wilds of North Carolina for much of the intervening time. Officials believe he must have had some help since, when arrested, he was clean-shaven and wearing new shoes. Rudolph was sentenced in 2005 to two consecutive life terms without parole. 

Smadi, Hosam Maher Husein. A Jordanian, was arrested in Dallas, Texas, on September 24, 2009, accused of trying to use a weapon of mass destruction to destroy an office building. Smadi entered the United States in 2007 on a tourist visa, a few months after his mother died of cancer. He first lived with family friends in San Jose, California, then moved to Italy, Texas, south of Dallas, where he worked as a cashier in a roadside restaurant. He appeared polite and friendly - he drank alcohol and liked dancing to Arabic "techno" music. According to friends in Texas, Smadi also went onto Internet chat groups where he expressed a desire to join jihad. His chats brought him to the attention of the FBI. In a case almost exactly like that of Michael Finton, undercover agents worked with Smadi, assuring him that they were contacts with Al Qaeda. On September 24, 2009, one day after Finton was arrested in an almost identical scenario in Springfield, Illinois, Smadi parked an SUV he thought was loaded with explosives in the parking garage under a Dallas, Texas, skyscraper, then dialed a cell phone he was told would detonate the explosives. After dialing the number twice, Smadi was arrested by the undercover agent and accused of trying to use a weapon of mass destruction. 

Shahzad, Faisal. A native of Pakistan who entered the United States on a student visa at the end of 1999 and became a citizen, Shahzad pleaded guilty in June 2010 to planting a car bomb in Times Square on May 1, 2010. He told a judge that he had acted as a "Muslim soldier" who had been trained by the Pakistani Taliban to revenge the deaths of people in Muslim lands at the hands of the United States. His guilty plea carried a mandatory term of life in prison. Shahzad's plot was foiled when the homemade bomb in his SUV failed to detonate. 

Lone wolf terrorist attacks showed no signs of abating throughout the 2010s and continued into the 2020s. On January 15, 2022, Malik Akram, forty-four years old and of British Pakistani descent, took hostages at a Texas synagogue. The hostages were later released, and Akram was fatally wounded by law enforcement. Akram was believed to be acting for the release of Aafia Siddiqui from prison. On May 14, 2022, eighteen-year-old Payton S. Gendron shot thirteen people, killing ten, at a Buffalo, New York supermarket. Gendron, a noted White supremacist and conspiracy theorist, traveled specifically to the area to target Black victims.

Active Shooters 

Active shooters were individuals who employed weaponstypically assault riflesto cause mass casualty events. Although not technically categorized as "lone wolf terrorists," in the past 30 years these individuals inflicted far more deaths and casualties on Americans than Lone Wolf terrorists. These killers were, almost without exception, native-born Americans. They also employed legally obtained weapons and ammunition.

On October 1, 2017, 64-year-old Stephen Paddock fired over 1,000 rounds at an outdoor crowd in Las Vegas, Nevada using a high-powered automatic rifle. Paddock killed 60 people and wounded 413. Some active shooters espoused racially motivated political views. Patrick Wood Crusiusa 21-year-old gunmanshot and killed 23 people and injured 22 others in a Wal Mart in El Paso, Texas in 2019. Anti-immigrant and Christian nationalist themes motivated Crusius. On May 24, 2022, 18-year-old Salvador Ramos killed 19 elementary school children in Uvalde, Texas.

Between the years 2006-2024, the United States experienced 476 gun-related mass killings. These events averaged 25 such events per year and claimed a total of 2,527 lives. In the first nine months of 2024 alone, 23 gun-related events occured. By the mid-2020s, guns were the leading cause of death for American children and adolescents. Guns attributed an estimated 1.7 deaths per 100,000 kids. Drug overdoses, car accidents, and diseases such as Covid-19 trailed in comparison.
