Authorities on Sunday confirmed the identity of the Darby Borough police officer who was shot to death in his home.

Chief Michael DiLenno of the Yeadon Fire Company confirmed in an interview with NBC10 the slain officer was Mark Allen Hudson, 26, a part-time police officer who also volunteered with Yeadon Fire Company No. 1.

"It was kind of an around-the-clock thing for him," DiLenno said. "He would come up in the middle of the night, after he would get off day work being in a police car all day, for a fire call. He just had a duty to serve and he always did it with a smile."

Police said that around 4:30 p.m. Saturday, Hudson was shot in the chest on the second floor of his house on the 600 block of Magnolia Avenue in Glenolden.

He was pronounced dead at Penn Presbyterian Medical Center.

Police have not yet said why the shooting occurred or who shot Hudson. A woman identified as Hudson's girlfriend was videotaped being taken from the house in handcuffs.

No one has been charged, and the shooting is being investigated by Darby Township detectives. Darby Borough police officials could not be reached Sunday.

Hudson had been a part-time Darby Borough officer for four years.
