On Monday, investigators identified the victim as Mario Villareal. His body was discovered at the WCA Waste Corporation transfer facility near the Beltway and Highway 59 last week.
Detectives say 11 trucks dumped trash at the site. The company was able to narrow down the number of trucks that possibly picked up Villareal's body to three.
Autopsy results to find out how Villareal died are pending.
