The death of a man whose remains were found at the site of the old DeAnza Drive-In in May has been classified as a homicide, police said.

Construction workers found the bones May 17 while working at the site near East 22nd Street and South Alvernon Way, according to a Tucson Police Department news release.

The Pima County Medical Examiner conducted a forensic examination on the remains before determining the death was a homicide.

The person was identified as a man between 45-60 years-old who was about 5-feet-7 inches with red hair and possibly a red beard.

Investigators believe the bones were at the drive-in for several years.

Homicide detectives are investigating the death.
