Lawrence Police are investigating the death of an unidentified man after a west Lawrence property owner found his body Thursday evening in the backyard of a duplex.

Lawrence Police Sgt. Mike Pattrick, head of the police detective division, released a statement late Thursday night saying that the cause of death had not been determined, but that the investigation had yielded no signs of foul play. An autopsy on the body will be performed today, he said.

Police arrived on the scene at 5:53 p.m. and blocked off the area with yellow tape. Later, they draped a green tarp over the patio fence to obstruct the view of the body through the wooden slats as several neighbors looked on.
