The Anchorage Police Department is investigating a hit-and-run that killed a pedestrian on Elmore Road Saturday morning.

Police said in a Nixle issued at 10:37 p.m. that they received a 911 call reporting the collision around 5:30 a.m. When they arrived at the scene on Elmore Road, they found a deceased woman and a witness just south of Lore Road, according to the Nixle alert.

The APD Major Collision Investigation Unit responded to investigate. The victim had been walking in the southbound lane of Elmore Road and was struck by a vehicle headed in the same direction, according to police. Additionally, forensics helped determine that the vehicle that struck her was a gray Chevrolet Sonic.

In an earlier Nixle, police said the vehicle involved was likely a metallic, dark grey, four-door sedan — a 2012 to 2014 model Chevrolet Sonic. Police said the vehicle would be missing its left side mirror and possibly has a damaged or malfunctioning headlight.

At 4:30 p.m., 30-year-old Brian E. Walter turned himself in as the driver to police, according to the most recent Nixle. He gave APD the location of his 2013 Chevrolet Sonic, which police impounded as evidence.

Police charged Walter with failure to render aid, which is a class B felony. He was taken to the Anchorage Correctional Complex and held under a bail of $5,000 cash corporate, police wrote.

Anyone with information on the collision, which is still under investigation, is asked to call police at 907-786-8900, or to submit an anonymous tip through Crime Stoppers at 907-561-7867.

The identity of the victim will not be released until her next of kin have been notified of her death.
