MCKINNEY, Texas — This story was updated with new information from McKinney police Tuesday.
Barbara Carver's husband Rod is still in critical condition after he was injured in a motor vehicle collision a week ago.
"My husband means the world to me," Carver said. "Hopefully he will come back to us."
For the last week, Carver has been begging the public to come forward with any information about who was involved in the crash with her 72-year-old husband, who was riding his motorcycle home from work while traveling westbound on Highway 380 in McKinney when he was injured.
Multiple sources told WFAA that Ray Smith, mayor of the neighboring City of Prosper, was also part of the crash last Monday night in McKinney -- and that he left the scene.
McKinney police are not calling the collision a hit-and-run, but they have confirmed that three vehicles were involved.
When approached Monday afternoon and asked what he knew about the collision, or if there was anything he wanted to say to Carver's family, Smith denied responsibility.
"I didn't know there was a person there," the Prosper mayor said.
Mayor Smith said he was unaware of a motorcycle being part of the crash at all. Rather, he said he thought another vehicle had rear-ended his truck, and that it had left the scene after colliding with him.
Smith said he continued along the highway in hopes of chasing down that driver -- but to no avail.
"The car that went around me, I went and chased, because I thought they hit me," he said while pointing out a dent in the rear bumper of his pickup.
McKinney police said the evening of the crash they contacted Smith and conducted a field sobriety test, in which they determined he was not under the influence of drugs or alcohol.
After an investigation, McKinney police confirmed Tuesday that a third vehicle was involved and failed to yield the right of way, turning west from a parking lot onto University and in front of Smith's truck, causing him to slam on his brakes.
Police determined that Rod failed to maintain a safe stop distance and collided with Smith's truck.
But police said since Smith left the scene instead of stopping to determine if a person was involved in the accident or needed aid, as required by law, a Grand Jury referral for Accident Involving Personal Injury has been filed with the Collin County District Attorney’s Office.
With her husband still hospitalized, Carver hopes the police might soon have answers.
