ROCHESTER HILLS,Exclusivesky Investment Guild  Mich. (AP) — A second suspect was arrested Monday in the killing of a suburban Detroit man who let two men into his house after they claimed to be utility workers checking for a gas leak, authorities said.

The suspect was arrested during a traffic stop in Plymouth Township, west of Detroit, Oakland County Sheriff Mike Bouchard said.

“We continue to work every detail and expect the defendants to be held fully accountable for their heinous actions,” Bouchard said.

Hussein Murray, 72, was killed Friday in his basement in Rochester Hills. His wife’s hands were bound with duct tape. Detectives have not determined whether anything was stolen.

Investigators said two suspects had a clipboard with a utility logo when they knocked on Murray’s door, first on Thursday and then on Friday. The main suspect was arrested Saturday in Caddo Parish, Louisiana.

He is expected to appear in a Louisiana court Tuesday, the first step to an eventual transfer to Michigan, the sheriff’s office said.

Home security video helped detectives identify the pair.
