HARRIS COUNTY, Texas — Deputies are investigating a homicide after a man was found dead inside an SUV at a car wash Wednesday morning.

Deputies say they received a call around 6:20 a.m. from family of Jaime Diaz concerned that something may have happened to him. Diaz, 44, was found unresponsive at a car wash located in the 4000 block of Aldine Mail Road in north Harris County.

Diaz lived in the general area.

Investigators say they are not sure what caused Diaz's fatal injuries but they do not appear to be self-inflicted. They added that there were definitely signs of trauma.

Deputies also ran the license plate of the SUV the victim was found in and it leads back to a man who lives in Katy. However, they do not think he is the owner of the vehicle.
