How an 18-Year-Old Colorado Man Humzah Mashkoor Became a Homegrown Terrorist

Humzah Mashkoor is an 18-year-old man from Castle Rock, Colorado, who was arrested on July 14, 2023, at Denver International Airport for allegedly attempting to join the Islamic State (ISIS), a designated foreign terrorist organization. According to the U.S. Attorney’s Office for the District of Colorado, Mashkoor pledged an oath of allegiance to the leader of ISIS and intended to serve as a fighter for ISIS in Iraq. He was charged with attempting to provide material support to a designated foreign terrorist organization, which carries a maximum sentence of 20 years in prison.
How did the FBI catch Humzah Mashkoor?
The FBI began investigating Mashkoor after an unnamed individual who knew him contacted the Douglas County Sheriff’s Office with concerns over his behavior. The individual reported that Humzah Mashkoor had previously followed white supremacist ideology but began practicing Islam, possibly as early as October 2020. The individual also said that Mashkoor began accessing more radical content online in early 2021.

The FBI then used two confidential sources to communicate with Mashkoor online and in person. One of the sources pretended to be a fellow ISIS supporter who shared Mashkoor’s radical Islamic beliefs and his desire to travel to Iraq to fight for ISIS. The other source claimed to be an ISIS travel facilitator who could help Mashkoor arrange his trip to the Middle East.
Over several months, Mashkoor obtained a passport and funding for his travel, researched and purchased various items that he believed he would need as an ISIS fighter overseas, and planned his migration. He also expressed his willingness to kill or be killed for ISIS and his hatred for the U.S. government and its allies.
On July 14, 2023, Humzah met with the second source at a hotel near Denver International Airport and received a fake itinerary and a fake ticket for a flight to Turkey, a common transit point for ISIS recruits. He then proceeded to the airport, where he was arrested by the FBI as he attempted to board the flight.
What do we know about his background and motives?
Humzah Mashkoor was born in the U.S. and lived in Castle Rock, a suburban town in Douglas County, Colorado. He graduated from Castle View High School in May 2023. He did not have a criminal record or any known ties to terrorist groups before his arrest.
According to the affidavit filed by FBI Task Force Officer Joni Tangeman, Mashkoor’s radicalization was influenced by his online exposure to ISIS propaganda and his personal grievances. He told the first source that he felt oppressed and discriminated against as a Muslim in America and that he wanted to live in a true Islamic state. He also said that he was inspired by the stories of other ISIS fighters who sacrificed their lives for the cause.
Humzah also expressed his admiration for Abu Bakr al-Baghdadi, the former leader of ISIS who was killed by U.S. forces in 2019. He said that he wanted to follow his example and become a martyr for ISIS. He also said that he wanted to avenge the deaths of his fellow Muslims who were killed by the U.S. and its allies in Iraq, Syria, and other countries.
What is the current status of his case and what are the possible outcomes?
Mashkoor made his first appearance in federal court on July 18, 2023. He was ordered to be detained pending trial. He will make a second appearance on July 22, 2023. He is being represented by a public defender.
If convicted, Humzah Mashkoor faces a maximum penalty of 20 years in prison, a $250,000 fine, and a lifetime of supervised release. However, he may also plead guilty or cooperate with the authorities in exchange for a lesser sentence. He may also challenge the evidence or the charges against him in court.
The case is being prosecuted by Assistant U.S. Attorney Gregory Holloway and Trial Attorney Alicia Cook of the National Security Division’s Counterterrorism Section. The case is being investigated by the FBI Denver Field Office, with assistance from the Douglas County Sheriff’s Office.
What are the implications and the reactions to his arrest?
Humzah’s arrest is a rare but alarming example of a homegrown terrorist who was radicalized online and attempted to join a foreign terrorist organization. It shows that the threat of ISIS and other extremist groups is not over, even after their territorial defeat and the death of their leaders. It also shows that the internet and social media can be used as powerful tools for recruitment and indoctrination of vulnerable individuals.
Humzah Mashkoor’s arrest has also sparked various reactions from the public and the media. Some people have expressed shock and disbelief that a young man from a peaceful and prosperous community could turn into a potential terrorist. Some have also questioned how he was able to evade detection and intervention by his family, friends, school, and law enforcement. Others have expressed sympathy and compassion for Mashkoor, saying that he was a victim of brainwashing and manipulation by ISIS and that he needs help and rehabilitation. Others have also called for more awareness and education about the dangers of radicalization and the signs of extremism.
His arrest has also raised concerns and questions about the security and screening of travelers at Denver International Airport and other airports in the U.S. Some have wondered how Humzah Mashkoor was able to obtain a passport and a ticket without raising any red flags. Some have also suggested that more measures and resources are needed to prevent and detect such cases in the future.
