Mercey-Marie Brasher, a 24-year-old White/Caucasian female from Riverside, California, was killed after a shooting on October 19, 2020, in San Bernardino. The violence unfolded at a home in the 500 block of Magnolia Avenue, where police were called to what investigators described as a suspected robbery. When officers arrived, they found Brasher suffering from multiple gunshot wounds.
She was taken from the scene to a hospital, but she did not survive.
The shooting was not limited to Brasher. A second person at the residence was also struck by gunfire and hospitalized, but that victim was released the next day. The available reports do not describe that person’s relationship to Brasher or explain why the home was targeted. What emerges from the public accounts is a sudden and violent encounter inside or around a residence, with Brasher caught in a robbery-related shooting that ended her life.
Investigators quickly identified a suspect: David Gilbert Colvin, 29, of San Bernardino. Police said Colvin was suspected in the shooting and arrested him on October 20, 2020, one day after Brasher was killed. He was booked on suspicion of murder. Authorities did not publicly explain what evidence led them to Colvin, and the available reporting did not describe whether he knew Brasher, the other shooting victim, or anyone connected to the Magnolia Avenue residence.
The case was publicly framed as a suspected robbery that escalated into deadly gunfire. Reports available online identified Colvin as the arrested suspect but did not provide a detailed motive beyond the robbery allegation. They also did not provide a full account of the sequence of events inside the home, whether anything was taken, or whether more than one person was believed to have been involved.
Online sources reviewed for this synopsis did not show a confirmed trial outcome, conviction, acquittal, plea, sentencing, or dismissal connected to Colvin in Brasher’s killing. The public record available through news-style sources appears to stop at the announcement of his arrest and booking on suspicion of murder.
