The Harris County Sheriff’s Office is investigating the shooting of a repairman found dead inside an empty Houston-area home Thursday.

HSCO Sgt. Gregory Pinkins said family members contacted the man’s employer after he went to work but did not return home. The company tracked his truck to a home on 12400 Crathie Dr. in Atascocita, where authorities found the man dead with at least one gunshot wound. 

Pinkins said authorities found shell casings inside the home, and they were working to obtain a search warrant to process the scene. The repairman was approximately 31-years-old, he said.

The homeowner’s son was expected to meet the repairman at the home around 3 p.m. to fix a leak, but it’s unclear whether he or someone else let the repairman in. Authorities had not spoken to the son as of Thursday.

Pinkins said deputies received information that a black sedan was seen leaving the home, which is not the vehicle that they believe the son drives. He said they are working on trying to identify the vehicle and who was inside.
