San Antonio -

The Bexar County Medical Examiner's Office says the body of an infant found this week at a San Antonio recycling center was a boy.

On Monday, a worker sorting items on a conveyor belt at a Waste Management recycling center found the baby's body inside a duffel bag.

The infant is believed to be between one and 10 days old.

The cause and manner of the child's death still aren't available.

Police say if the medical examiner's office determines the baby was not stillborn, their investigation could become a capital murder case.
