The Dallas man was riding a dockless electric scooter home after work in East Dallas around 2:30 a.m. Sunday.

His family tells CBS11, Stoneking called his roommate saying he’d fallen off a scooter.

Paramedics arrived and took Stoneking to the hospital, but he died from his injuries.

His scooter was found broken in half about 100 yards away from where he was lying on the ground.

“I asked him if he was hurt, he said ‘no, I hurt my foot.’ I go to the hospital and he’s on breathing tubes and everything,” said Kenny Moore, Stoneking’s roommate.

Dallas Police are looking into concerns a car may have been involved, but the debris at accident location belonged to the scooter.

“My absolute instinct about this- this was not just about an accident about him and a scooter,” said Stoneking’s brother Chris Phillips. “I think someone else was involved.”

Stoneking was not wearing a helmet.
