SIMI VALLEY >> A gunman who told his brother he shot their mother, then fired shots in her quiet Simi Valley neighborhood and fled on a tractor before he was shot dead by police Saturday has been identified as 29-year-old Ryan Carnan, authorities and witnesses said Sunday.

A deceased woman, who has yet to be identified but is believed to be the mother, was pulled from Carnan’s mother’s home Sunday morning in the 1100 block of Mellow Lane.

Simi Valley Police said Carnan’s brother told police about 4:45 p.m. Saturday that Carnan had called to tell him he had shot their mother at her home. A portion of the house “was engulfed in flames” when officers arrived at the scene, said Simi Valley Police Cmdr. Stephanie Shannon.
