Los Angeles County police found a dead third-trimester baby near a trash can on Friday morning, authorities say.

Los Angeles County Sheriff's Department deputies were called to the Whittier Narrows Recreational Area to investigate the incident. They found a premature male infant with an attached umbilical cord next to a trash can.

The body was found lying face-down near a grassy area of the South El Monte park. Investigators are unsure if the baby was alive before he was discovered.

"The infant appeared to be 7 months old in the third trimester of the gestational period and fully developed," the Los Angeles County Sheriff's Department said in a statement.
