GEORGETOWN, Texas (KXAN) — A 20-year-old man is in jail accused of hitting and killing a 19-year-old Georgetown bicyclist and leaving him on the side of the road earlier this week.

Georgetown police say Aaron Davison is charged with accident involving death in connection with Thomas “Tommy” Ketterhagen death. Davison turned himself in on Friday morning.

Ketterhagen was last seen riding his bicycle in east Georgetown around 5 p.m. Monday. When he didn’t return home that evening, his family reported him missing. On Tuesday morning, his mother found his body in the 2300 block of Patriot Way.

“To see his body there on the grass and see his bike just crashed to smithereens, it was awful. But I was thankful I got there first, that I was able to hold him, talk to him and just be with him,” said the victim’s mother Luz Ketterhagen.

A witness told police he saw a dark blue pick-up truck driving erratically around SH 130 and take a left on Patriot Way around 6:30 p.m. Monday. The witness said he saw the truck drive into the wrong lane and strike a bicycle. While the witness couldn’t tell if anyone was on the bicycle, he did, however, see a bicycle wheel and a bike fly in the air. After impact, the witness said two people got out of the vehicle and started looking around a ditch and “accelerated out of the area,” police say.

With the information they received from the witness and evidence left at the scene, detectives started searching their records for any 1998-2000 Chevy Silverados that have a history with law enforcement. A match came back to one dark blue Chevy Silverado in the Hutto-Georgetown area. When officers went to check on the vehicle, they found that it had damage to the driver side fender and a missing driver side headlight.

On Thursday, Davison provided a written statement to authorities admitting to driving the vehicle that was involved in the crash. “Mr. Davison also wrote that once he became aware that a bicyclist was killed on the same road, he realized he was likely responsible for the death of the person,” said Georgetown police spokesperson Roland Waits.

Davison’s attorney, Joe Turner, says his client was not drinking, but that he dropped his phone and reached down to get it and that’s when he thought he hit something. Turner goes on to say that when Davison stepped out of the truck to look around, he said he didn’t see anything and proceeded to get back into his truck.

“It wasn’t until the next day that they found out that there was actually a death, and that’s when it dawned on them and said ‘we got to come forward, we got to the right thing,” explained Turner.

Ketterhagen was an avid cyclist and rode with several bicycle groups. On Sunday, Jan. 29, a memorial bike ride is being held to honor Ketterhagen. The ride starts at 10 a.m. at East View High School. Details on the route can be found here.

Friends have also started a GoFundMe page to raise money for the family.
