A Kaiser Permanente employee was struck and killed when a pursuit suspect struck him near the hospital where he worked in Riverside.

What we know:

Officers initially attempted to stop a driver around 11:40 a.m. Monday for an alleged vehicle code violation, according to police. 

Although the driver initially yielded, they ultimately took off and went down Magnolia Avenue, leading to a police chase.

During the pursuit, the driver struck 42-year-old Peter Mullis near Kaiser Riverside Medical Center. 

Mullis was taken into the medical center, where he died from his injuries. 

Following the incident, authorities temporarily closed eastbound Magnolia Avenue between Skofstad Street and Polk Street, along with all lanes on Park Sierra Drive, for several hours to conduct their crash investigation.

The suspect, Gene Amos Cunningham, has since been arrested in connection to the deadly crash.

What they're saying:

"Peter was a beloved husband, family member, and friend whose loss has left an immeasurable void in the lives of everyone who knew and loved him. Most of all, he leaves behind his devoted wife, Layla, who is now facing the unimaginable heartbreak of moving forward without her husband," a verified GoFundMe campaign read.
