Los Angeles police ID Shawn Laval Smith as suspected killer of Brianna Kupfer

Los Angeles police have identified Shawn Laval Smith as the suspected killer of 24-year-old Brianna Kupfer, a UCLA grad student stabbed to death at her furniture store job last week.

Los Angeles County Jail records show Covina police arrested him on Oct. 27, 2020, on a misdemeanor charge. He was released on $1,000 bail. The outcome of that case was not immediately clear.

A law enforcement source tells Fox News Digital that Smith has a rap sheet that spans both coasts, including in San Francisco and South Carolina. His most recent charge is allegedly for shoplifting -- and he landed up in jail in San Mateo after allegedly assaulting a police officer.

Los Angeles District Attorney George Gascon's office did not immediately respond to a request for comment.
