On February 26, 2023, at about 3 p.m., officers responding to a traffic accident near 8th Street and U Street in Rio Linda heard gunfire and found 42-year-old Russell Mawyer in the driveway of a residence at 801 U Street with multiple gunshot wounds. Deputies and Sacramento Metro Fire personnel performed life-saving efforts but Russell was pronounced dead at the scene.

Family members identified Russell’s brother, 39-year-old Robert Mawyer, as the primary suspect, saying the brothers had been engaged in frequent disputes in the weeks before the shooting. Relatives reported that Robert fled the scene by stealing a car. Two people at the residence were initially detained and later released when investigators determined they were not involved. Detectives arrested Robert Mawyer on suspicion of murder and he was booked into Sacramento County Main Jail; he was scheduled for a court appearance on March 8, 2023. The motive remains unclear.

Did anyone in the Rio Linda area see the brothers together in the days before February 26, 2023, or have information about what led to the dispute?
