The Texas Department of Public Safety is asking for the public’s assistance in locating a vehicle connected to a fatal hit-and-run collision outside Gainesville last week.

An emailed press release distributed by DPS Monday said the wreck occurred shortly before 9 p.m. last Friday near the intersection of FM 678 and County Road 219, five miles east of Greenville. DPS Staff Sgt. Mark Tackett said a dark-colored Ford F-250 pickup was traveling east on FM 678 when the driver of that vehicle allegedly failed to control his speed through the intersection and struck David Smith, 63, of Gainesville, as he rode his motorcycle.

“(The driver) failed to stop and render aid whenever they hit him,” Tackett said in a phone interview Monday.

Smith was transported to Medical City of Denton for treatment but later died from his injuries. Tackett said the agency’s investigation indicated the driver of the pickup was at fault in the collision, but left the scene.

The DPS release described the four-door truck as being black or dark gray in color and having front-end damage, tinted windows and a regular-length utility bed. Tackett said, as of Monday afternoon, investigators were unable to provide a description for a possible suspect, but added the agency would continue to follow up on leads.

“It’s important that every case is solved to a full result so that we can conduct an accurate investigation and provide closure to the family,” Tackett said.

Those with information related to the investigation are encouraged to call the DPS Gainesville field office at 940-668-5417.
