The man suspected of placing a failed explosive device inside a Jefferson County mall last week will make his first appearance in federal court tomorrow afternoon.

Earl Albert Moore, 65, was arrested this morning in Boulder after someone spotted him drinking coffee at Starbucks inside a King Soopers, sources said.

Moore was arrested shortly before 7:30 a.m. at the King Soopers at Table Mesa Drive and Broadway, Boulder police spokesperson Kim Kobel said.

A woman in the store noticed Moore drinking coffee around 6:30 a.m. and told a manager, who called 911, Kobel said.

The woman recognized Moore from news reports.

When Moore realized police were coming into the store in pursuit of him, he tried to leave but was apprehended in the parking lot.

Moore was unarmed and complied with the officer’s orders to get on the ground. After he was frisked and handcuffed, Moore gave officers a fake name, Kobel said.

Moore remained in a patrol car until he was turned over to the FBI.

Authorities released few details during a briefing for the media in Jefferson County this afternoon, but said Moore would remain in federal custody at least through tomorrow’s court appearance. Details of the charges against him remain sealed.

Last Wednesday’s incident at Southwest Plaza occurred one week after Moore was released from federal prison for a 2005 bank robbery in West Virginia.

His criminal record also includes multiple larceny convictions, a drug offense and reckless driving. Court records show he also had financial problems leading up to the 2005 bank robbery.

Moore lived in Colorado for several years prior to the bank robbery, according to public records, though police searched his prior residences and did not locate him there.

It is unclear what connection, if any, he has to Boulder or how long he had been there.

King Soopers spokeswoman Kelli McGannon said King Soopers has security cameras that were able to identify all the areas in the store that Moore had visited before having coffee. Security staff have made sure the building is safe, and no suspicious devices have been found.

Moore is expected to face federal charges.
