BALTIMORE, MD -

Prison officials in Maryland are explaining why they released a suspected killer from Bucks County.

Dale Wakefield was arrested in Baltimore in July for the stabbing and beating of George Mohr in Doylestown.

Just hours after Wakefield was arrested he was released by the Baltimore Detention Center.

Police nabbed him just before he arrived at the college dorm room of his sister.

She phoned in the tip that led to his initial arrest.

Mohr later died from his injuries and Wakefield was charged with first degree murder.

Maryland public safety officials say they "regret the data-entry issue that led to the mistaken release of Wakefield."

They say complications arose due to the nature of out-of-state warrants and detainers.

They say they're evaluating their processes and expect to take appropriate disciplinary action.
