Billy Stroud, 56, was riding a new motorcycle on Tuesday morning when he was struck from behind on Belknap Street in Haltom City, police said.
The driver who hit him, Tammy Sue Stegall, 50, was charged with murder. Police said she was previously convicted twice of drunken driving. Investigators said she was again driving under the influence when she struck Stroud.
Stroud's son Jonathon, 20, died after serving just two months as a Marine in Afghanistan. He was buried Saturday in Cashion, Okla.
His family was impressed by a group of motorcyclists called The Patriot Guard who attended the funeral. The group lines funeral routes of fallen soldiers all over the country.
"(We were) highly impressed,” said Johnathon's father-in-law, Jim Light. "I thanked each and every one of them."
Billy Stroud was so impressed, he bought a motorcycle Monday after returning from the funeral. He also applied to join the Patriot Guard.
