Baton Rouge police are investigating the May 26 death of a 59-year-old homeless man that was initially thought to have been of natural causes as a homicide following results of an autopsy.

Police found John Tallant under the I-12 overpass in the 1900 block of O’Neal Lane at about 5:30 p.m. that day, said Baton Rouge police spokesman Cpl. L’Jean McKneely.

Tallant was believed to have died of natural causes, but an autopsy revealed the actual cause of death was blunt force trauma to the head, McKneely said.

Anyone with information on the incident is urged to contact the Violent Crimes Unit at 389-4869 or Crime Stoppers at 344-7867.
