The coroner’s office has determined that what appeared to be a set of lungs found on a sidewalk Sunday afternoon in the Compton area were from an animal.

A woman walking in an unincorporated area of the county made the discovery Sunday afternoon in the 13100 block of Avalon Boulevard, took a picture of what she found and in the evening contacted the Los Angeles County Sheriff’s Department, said Lt. Jack DeMello of the sheriff’s Century Station. It was the only call the department received about the organs, he said.

“It was right there on the sidewalk at the start of a driveway,” DeMello said. “You’d think someone would see someone throw it out there.”

The coroner and crime lab responded to collect the lungs and any other evidence, he said. Blood and tissue samples were used to determine that the lungs weren’t human.
