The body was found outside of Charlie's Certified Transmission in the 7000 block of N. Shepherd Drive between Rittenhouse Road and Granville Drive, just south of West Little York.
According to homicide investigators, the man has been identified as 50-year-old Roy Scott of Houston, the owner of the transmission shop.
There are still a lot of questions surrounding Scott's death. Police say he was shot once. There are no suspects and no witnesses have come forward.
Scott's family and neighbors just want to know why it happened.
As word spread of Scott's violent death, neighbors and friends rushed to his north Houston transmission shop to see what happened. No reactions were as gut-wrenching as those of his wife and teenage daughter.
"She's crying. She's devastated right now. Everyone is," said Vanessa Portillo, Scott's daughter's friend.
According to the Houston Police Department, someone who works at a nearby business walked by between 8 and 8:30am and saw Scott's body in a pool of blood. That person dialed 9-1-1, but Scott was already dead.
"It appears he'd been there for several hours," HPD Homicide Sgt. C.D. Howard said.
Investigators are canvassing the area and trying to retrace the shop owner's steps to pinpoint exactly when Scott arrived, and whether he was scheduled to meet anyone.
Neighbor Ruth Portillo says she was one of the last to see him alive. She spotted him on their street at 12:30am.
"My husband and I said 'hi' to him and then he left again," she said.
Neighbors say Scott loved building race cars. Is it possible he came here to work on one? His family may never know.
According to police, Scott's shop was closed and locked up. His cell phone and wallet were still on him when authorities searched his body.
Investigators may be looking for Scott's white Ford pickup truck. They're not sure if he let someone borrow it for a job or if it was stolen as part of this incident.
His wife told us he installed surveillance cameras after recent robberies, but police don't believe the cameras were rolling overnight.
So, who would want to hurt Scott?
"I don't know," neighbor Dale Singletary said. "All of their family and him, they're really nice people. Real good people."
There are still no arrests in this case and the investigation is ongoing. Anyone with information is asked to call HPD or Crime Stoppers at 713-222-TIPS. All tipsters remain anonymous.
