A man recently released from a three-year prison sentence for attempting to rob a Casper bank is going back to prison for violating the terms of his probation, according to federal court records.

Jack Taber pleaded guilty in May 2014 to attempting to rob the Wells Fargo Bank in downtown Casper in March 2014.

Chief U.S. District Court Judge Nancy Freudenthal sentenced him to 37 months of imprisonment, ordered three years of supervised release after his prison term, a mental health evaluation, and placement at a facility had has a drug and alcohol rehabilitation program.

Taber was serving the last several months of his sentence at the Casper Re-entry Center starting in late December. His three-year probation term began after that.

But beginning in May, the U.S. Probation Office reported a series of violations of the terms of his probation, mostly about alcohol consumption and failing to report for drug testing.

On Aug. 31, the Probation Office issued a warrant for Taber's arrest, and he was taken into custody.

On Thursday, Taber admitted to two violations and the government dismissed four others.

Freudenthal sentenced Taber to five months of imprisonment. After that, he will be placed on supervised release for 30 months, with the first three months to be served in a residential re-entry center.

The original case began March 26, 2014, when Taber entered the Wells Fargo Bank at  First and Durbin streets. He told a teller that he was robbing her, that he was watching her, and did not want to hurt her.

He told the teller not to push any alarms and to put the money into a bag.

The teller told Taber she did not have a bag and needed to get one from the back room.

In the back room, she alerted another employee who called police.

Taber left without any money, and was seen a few hours later at the Natrona County Public Library and was taken into custody.

When questioned, he admitted he was in the bank, and didn’t know why he did it.
