AUSTIN – Police have charged a man with striking a woman with his car in northwest Austin on Jan. 6 and leaving the scene.

Tommy McGrew, 29, was charged Tuesday with felony failure to stop and render aid. He allegedly struck Katherine Snodgrass the evening of Jan. 6 near the intersection of Lakeline Mall Drive and North Lake Creek Parkway.

Officers arrived at the scene around 11:15 p.m., and Snodgrass was taken to Round Rock Medical Center, where she died. Police said three bystanders were tending to Snodgrass when they arrived, and an officer identified McGrew as one of the bystanders.

Around 3:30 a.m. on Jan. 7, McGrew called 911 and “stated he struck what he thought was a deer,” the affidavit states. Officers met with McGrew and one of the other initial bystanders, and observed McGrew’s Chevrolet Cruze had collision damage consistent with the crash that same evening. The other bystander told police that McGrew woke her up and “told her that he had hit something and they needed to go back to see what he had hit.” When McGrew and the bystander had returned to the scene, they found Snodgrass at a bus stop and called 911.

The bystander told police she was in shock when officers first spoke to them and did not know what to do. The affidavit said McGrew contacted an attorney after they were initially released, who advised him not to call police. The bystander later reported their involvement.

The third bystander was not involved in the crash, police said.

McGrew was booked into the Williamson County Jail. Online records show he is being held on $20,000 bond as of Tuesday afternoon.
