Guillermo M. Romero, a 42-year-old Latino man, was fatally shot on December 22, 2019, near the 300 block of Witmer Street in the Westlake neighborhood of Los Angeles. The Medical Examiner-Coroner recorded his death on December 30, 2019. He was found with gunshot wounds that proved fatal.

The Los Angeles Police Department investigated the killing as a violent crime. The inquiry faced challenges including the need for witness cooperation and collection of evidence to identify and prosecute those responsible. Arrests were later announced and charges were brought, including murder, attempted second-degree robbery, and firearm possession by a felon; one defendant was charged with first-degree murder with an allegation the killing occurred during an attempted robbery.
