Authorities said Tuesday that a man whose body was found near railroad tracks on East Eighth Street was in his 50s.

As yet authorities do not know the cause of death. The body was taken to the coroner’s office, where an autopsy was scheduled for Tuesday, Lawrence Police spokesman Sgt. Trent McKinley said.

Lawrence police reported finding the body about 4:15 p.m. Monday, after they were dispatched to the rail yard. The body was close to an inactive section of track, police said.

The original call broadcast over the police scanner reported a possible dead person or “cardiac arrest” near 730 E. Eighth St.
