FORT WORTH, Texas (CBSDFW.COM) - A man who was cleared by Fort Worth police as having acted in self-defense when he killed his neighbor last month, is now behind bars.
Mark Jabben, 46, was arrested in an unrelated shooting case.
He was booked Friday into the Tarrant County Jail on a charge of aggravated assault against a family member with a weapon.
Jabben is accused of shooting his girlfriend Theresa Ryan.
In March, Jabben shot his neighbor, Kevin Battle, in the face and back of the head -- killing him. It happened while Battle stood, holding his grandson's hand on the front porch of a duplex where they both lived.
Police said they believed Battle attempted to walk in to Jabben's apartment during an argument.
