A Texas repairman called the police after finding a human remains inside a backyard grill at a home he'd been contracted to work at on Tuesday, authorities say.

Police later arrived to the scene with a search warrant and confirmed there was a body inside a large BBQ grill. Houston Police said there was a full skeleton inside, but the remains were quite old, and they could not yet identify whether it was male or female, according to local media.

Police opened an investigation and are waiting for results from a medical examination of the body. No charges have been filed in connection with the incident, but homicide investigators are now on the case.

It is not clear whether the home is currently occupied.

The man and his wife were arriving to their home with their two children just after midnight Sunday evening when the two teenage suspects approached their SUV. The Harris County Sheriff's Office said that the suspects attempted to open the vehicle's rear door, where the two children were seated.

"The adult male feared for the safety of his family and fired shots and struck both suspects," Sheriff Ed Gonzalez wrote in a statement. "The wife was driving and drove away after the shooting to get away from the suspects."
