Attack At Colorado Supermax Prison Leaves 3 Staff Members Injured

Three federal prison staff members are recovering from injuries sustained during an attack on Wednesday by an inmate at the Supermax prison in Florence, Colo., a federal prison housing some of the nation's most dangerous prisoners.

According to Denver's KUSA, officials at the Federal Bureau of Prisons say that an inmate assaulted a prison staff member using a homemade weapon around 7 a.m. on Sept. 11. Other prison staff responded to the attack and were able to restrain the inmate.

“Additional staff immediately responded and all were able to quickly restrain the inmate. All three staff members were transported to a local hospital for evaluation and treatment of non-life threatening injuries,” prison spokesman Randy Mitchell said to Pueblo Chieftain.

Officially called the Administrative Maximum (ADX), but more commonly known as Supermax, ADX Florence or the "Alcatraz of the Rockies," the 37-acre Colorado prison first opened in 1994 and houses about 500 male inmates who are considered to be too dangerous or too great a national security risk for even a maximum-security prison.

Some of the country's most dangerous and well-known prisoners count themselves as residents at ADX Florence, including 9/11 attack planner Zacarias Moussaoui, Timothy McVeigh's co-conspirator in the Oklahoma City bombing Terry Nicols (McVeigh himself was housed at ADX until he was sentenced to death), 1993 World Trade Center bombing conspirator Ramzi Yousef, serial bomber Ted Kaczynski and many more.

Although the assault occurred on the 12th anniversary of the 9/11 terrorist attack in New York City, it was unknown if it was motivated by the anniversary.
