Earl Albert Moore, 65, served a federal prison sentence for bank robbery and was released just seven days before authorities believe he left a poorly crafted bomb in a stairwell in Jefferson County’s Southwest Plaza Mall.

Authorities found a small fire, two propane tanks and a crude pipe bomb on Wednesday, the anniversary of the Columbine High School massacre, which prompted mass evacuations and put a community on edge.

Records from the Federal Bureau of Prisons show Moore was released from custody April 13 and remained on supervised parole at the time of the alleged bomb attempt.

Court records show he robbed a West Virginia bank of $2,546, assaulted a bank employee and used a deadly weapon in the course of the 2005 robbery.

He was originally sentenced to 18 years in federal prison, but had his sentence reduced in 2008.

The FBI Denver Joint Terrorism Task Force has launched a nationwide manhunt for Moore, who they consider armed and dangerous.

The task force and the Jefferson County Sheriff’s Department asked the public to call 911 if they see Moore and report information regarding his wherabouts to the Jeffco Tip Line at 303-271-5615 if they have information regarding his whereabouts.

New photos show that Moore is bald with blue eyes, between 6-feet and 6-feet-two-inches tall, and weighs around 225 pounds.

He has several tattoos including a Viking head on one forearm and a heart and dagger on the other. He has a rose-like flower on his upper arm.

He was last seen wearing glasses, a gray mustache and a dark ball cap with a light-colored logo.

Moore’s criminal record in Colorado dates back to 1984 with a drug possession charge. He served six months in state prison on a felony burglary charge out of Arapahoe County in 2004.

At the time, he used the alias Earl Albert Buchannan. According to the Colorado Bureau of Investigations, Moore has also used variations of the names Donald Charles Morelli and Gary Steele.

In 2010, the state filed a distraint warrant in Jefferson County in an attempt to collect $2,819 in taxes from Moore.

Photos released by the FBI Denver Joint Terrorism Task Force and the Jefferson County Sheriff’s Office show Moore with tattoos of a heart and dagger, a rose-like flower and a Viking face on a bicep and forearms.

Surveillance photos show a man believed to be Moore entering a mall hallway typically used by employees around 11:43 a.m. Wednesday. Nine minutes later, a security officer discovered a fire in that same hallway.

The mall was evacuated after the fire was extinguished and two propane tanks were discovered.

A sweep of the mall also uncovered a poorly constructed pipe bomb near the tanks.
