NASHVILLE, Tenn. (WKRN) – A reward to help find a suspect who shot and killed a man during an apparent road rage shooting on Interstate 24 on Christmas Day has been increased.

On Wednesday, May 24, the Metro Nashville Police Department announced a reward of $20,000 for any information regarding the murder of Christopher “Chris” Spaunhorst.

Police said Chris was on his way home to Greenbrier when he was killed in an alleged road rage shooting on I-24 near East Nashville on Dec. 25, 2022.

After the shooting, Chris’ pickup truck collided with a median wall at the James Robertson Parkway exit. Authorities said the suspected vehicle continued driving westbound on I-24.

According to police, the gunshots came from a black sedan with chrome trim.

Detective William Mathis said officials believe the suspected vehicle is a 2016 to 2020 black Kia Optima.

At a press conference, Mathis stated that authorities have yet to receive any information to help determine the owner of the Optima or identify the individuals who were inside the Optima during the incident.

Earlier this month, officials announced a reward of $15,000, encouraging anyone with information regarding the shooting to come forward. 

Chris’ widow, Stephanie Spaunhorst, spoke at Wednesday’s press conference, urging anyone with information to come forward. 

“Thank you for all the prayers, calls, texts, the news channels for reaching out, the private donations. If you know anything, please come forward,” Stephanie said through her tears.

Afterwards, Stephanie spoke with News 2.

“Coming in today, I didn’t hit any traffic until I was right there beside it. It’s hard because you can see where his car drug across,” Stephanie said.
