Lawrence police are trying to determine the cause of death of a 52-year-old Lawrence man who was found Tuesday morning in a Lawrence hotel room.

Sgt. Matt Sarna, a police spokesman, said police were called at 9:10 a.m. Tuesday to the Howard Johnson Hotel, 2222 W. Sixth St., after someone found the man unresponsive. The man’s name was not released.

“Detectives are currently working at the crime scene and attempting to contact potential witnesses to determine the events and circumstances surrounding the incident,” Sarna said. “The cause of death has not been determined at this time.”

Forensic investigators Tuesday evening could be seen in the hotel’s parking lot dusting beer cans for evidence.

Officers asked anyone with information to call police at 785-832-7650 or Douglas County Crime Stoppers at 785-843-TIPS (8477).
