Jasper County investigators say they're receiving dozens of leads that could lead to an arrest in the shooting death of Curtis Shaun Hubbard.
As of Monday night, no suspects have been named in the murder.
The 33-year-old man was found shot to death inside his Ford Excursion early Sunday morning off Farm to Market 3414 in Jasper County.
An autopsy has confirmed that Hubbard died from a gunshot wound to his back.
Jasper County Sheriff Mitchell Newman tells 12 News HD that his deputies found Hubbard "slumped over on the steering wheel."
The sport utility vehicle was found littered with bullet holes and broken glass.
Investigators looked at evidence that spanned a half-mile along FM 3414.
"He hit a road sign and went over a couple culverts," said Sheriff Newman. "Right now, we're not really sure where the shooting took place."
Ella Simms lives right across the street from the crime scene.
"I immediately went crazy," said Simms. "I was shocked when I saw the crime scene."
Simms said she heard multiple gunshots and a loud crashing sound.
"I thought it was coming from the television," she added. "I heard the gunshots!"
A family friend tell 12 News HD that it was about three weeks ago, when someone fired shots at Hubbard's Ford Excursion. For some unknown reason, that shooting was never reported..
As for Sunday's early morning shooting, investigators tell us that Hubbard was last seen at several house parties in Jasper..
Family and friends tell 12 News HD that when Shaun wasn't spending time with his wife and three young boys, he was working here at his downtown Jasper barber shop.
Longtime friend Teresa Johnson describes Hubbard as a family man, which is why she doesn't understand this tragedy.
"They left this boy with a wife and three boys to take care of," she said. "Who going to take care of them? Nobody!"
Investigators are not sure who is responsible for this shooting, but they think that multiple weapons, possibly a high-powered gun, were used in this fatal shooting.
Funeral plans are still pending.
