Update: The Los Angeles County Coroner's office says the lungs found on the sidewalk were not human.
Investigators in California will breathe a little easier once they find out why a pair of lungs were discovered on a south Los Angeles sidewalk over the weekend.
FOX News Radio's Jessica Rosenthal explains:
A woman called Sheriff's officials Sunday to say she'd found organs on a sidewalk. The L.A. County Medical Examiner's Office says they're lungs. They don't know if they're human or animal, but hope to have more answers tomorrow (Tuesday) after some testing.
A lieutenant at the Coroner's Office says they don't know where they came from, and it is possible that they were a part of a study or maybe came from a medical school.
