HARRIS COUNTY, Texas - Harris County Sheriff’s deputies are looking for the driver who hit and killed a 64-year-old Houston veteran, then kept going.

It happened the night of March 8 as Larry Foster Williams was walking along Lee Road near Dwyer Drive in northeast Houston.

“He was a family guy. He loved his grandchildren. He loved the Lord,” said Gwendolyn Willis, Williams’ daughter. A week after his death, she and her family want answers.

“My father was a U.S. veteran. He deserved to be respected and honored. So for someone to leave him on the street like he was nothing it really hurts,” she said.

Foster’s death is part of an alarming statistic. According to a KHOU analysis of Texas Department of Transportation statistics, 75 percent of deadly hit-and-run cases that happened throughout Harris County in 2016 and 2017 remain unsolved.

“Witnesses are key factor in solving most crimes,” said Harris County Sheriff’s Office Sgt. Cedrick Collier in a statement. “With a lack of potential witnesses and vehicle evidence in this case, it doesn’t leave us with any viable leads to pursue.”

The Army veteran’s family hopes his case will be solved when the person responsible comes forward.

“I forgive you already, but I would like you to know that we all have to face justice for something that we do,” said Tyrone Williams, the victim’s son.

The family is offering a $1,000 reward for information leading to an arrest in this case in addition to the $5,000 reward from Crime Stoppers. They hope it will compel someone to offer more information about what happened to Williams.

“If it was your family, how would you feel?” asked Willis. “I’m asking for justice for my dad.”
