Police in Bloomington are investigating the death of a homeless man who was found beaten to death by the railroad tracks.

McLean County Coroner Beth Kimmerling says preliminary autopsy results show that 48-year-old Robert Jeronimus died of multiple blunt force injuries. Toxicology tests are still pending.

Authorities say a public works employee found Jeronimus' body Thursday.

He's the second homeless man killed in Bloomington in the past three weeks. Authorities say a 45-year-old homeless man was struck and killed by a truck while sleeping near a gas station on July 29. That case also remains under investigation.
