It reported Brian Mathew McColley, 49, was arrested Tuesday in El Cajon, that detectives located him about 4 p.m. in the 300 block of Cedar Street, and that he was booked into San Diego Central Jail on suspicion of murder and the unrelated warrant. Cedar St., on the police release, and Cedar Street, on NBC 7 and Patch, are the same block with a different abbreviation. About 4:00 p.m., and about 4 p.m., and at 4 p.m., are not the same rounding.

The police release reported that shortly after 2:00 a.m. on Monday, October 5, 2026, Quiroz-Arreola, 31, was shot and killed at Crystal Pier in the 4500 block of Ocean Blvd. in Pacific Beach.

Aberto Quiroz-Arreola, and Luis Alberto Quiroz-Arreola, are not the same name. The police release, CBS 8, and Patch print Luis Alberto Quiroz-Arreola. The Aberto spelling is on NBC 7. It is not the spelling in the release. Shot and killed, on the police release, died at the hospital, on CBS 8, and pronounced dead after paramedics took him to a hospital, on NBC 7, are not the same medical line. Shortly after 2:00 a.m., on the police release, and shortly after 2 a.m., on Patch, are the same hour with a different rounding. CBS 8 and NBC 7 do not print the 4500 block.

The booking those pages describe is on suspicion of murder, plus a warrant the department calls unrelated. The release does not print the unrelated offense. CBS 8, NBC 7, and Patch do not print it either. The police release asks anyone with information to call the Homicide Unit at (619) 531-2293 or Crime Stoppers at (888) 580-8477. CBS 8 prints those same numbers. NBC 7 prints 619-531-2293 and 888-580-8477. Patch prints the Homicide Unit at 619-531-2293 or San Diego County Crime Stoppers at 888-580-8477.
