Shortly before 9 p.m., Margot Kellum was walking in a crosswalk on Speedway Boulevard near Richey Boulevard when she was hit by a vehicle.
Kellum died shortly after arriving at a hospital, a police news release said.
Detectives determined the incident occurred during a monsoon storm. Kellum was southbound in the crosswalk when the Jeep Wrangler heading east on Speedway Boulevard struck her.
The driver remained at the scene and told police they didn’t see Kellum in time to avoid the collision.
It does not appear speed was a factor, the news release said. Impairments have not been determined.
No charges or citations have been issued in the ongoing investigation.
Anyone with information about the incident is asked to call 88-CRIME, an anonymous tipster line.
