CHELTENHAM, Pa. (CBS) — In a crime that authorities believe was sparked by jealousy, a Philadelphia man today admitted his part in the Christmas Day 2011 murder of a man who was wrapping presents with his girlfriend inside her Cheltenham Township (Montgomery County) home.

Ezra Childs pleaded guilty to third-degree murder and carrying a firearm without a license, and agreed to testify against the man whom police say orchestrated the murder of 25-year-old Robens Borno.  Borno was gunned down as he wrapped Christmas gifts inside his girlfriend’s Beech Avenue home.

Defense attorney Brendan Campbell says Childs, 22, wants to take responsibility for his role in the crime but notes that his client didn’t pull the trigger.

“The statement will state that he did have a firearm on him, he had it out of his pocket at the time, in his hand, at the time that the victim was shot,” Campbell tells KYW Newsradio.

Police say Rayshon Carwheel shot Borno because he was dating Carwheel’s former girlfriend, the mother of his child.

Carwheel is scheduled to go trial later this year.

According to sentencing guidelines, Childs is facing the possibility of seven to 22 years behind bars.
