SAN DIEGO - Three girls playing Pokemon Go at Marian Bear Memorial Park discovered a body Thursday afternoon, police said.

The discovery off the 5500 block of Regents Road was reported shortly before 3 p.m., according to San Diego police.

Police told 10News they believe the person is homeless and died of natural causes.

Apryl Lopez was one of the girls who found the body.

"I froze, stopped in my tracks, looked my friend and my sister in the face and said, 'I think I just found a dead body,'" Lopez said. "I looked down and I saw the legs, the bones of a dead body with no feet and no ankles and it looked like they had been chewed."
