Mohammad Shirazi, 48, of West Hills, California, was reported missing on May 1, 2008. The case shifted from a missing-person investigation after Mohammad’s father returned from a trip to Iran and could not find him at the family home, which had been under the care of Mohammad and his brother Hossein Shirazi.

Investigators found biological evidence, including blood in the living room rug and on furniture, and treated the disappearance as a homicide despite no body ever being recovered. Hossein Shirazi was later arrested and charged with Mohammad’s murder; authorities alleged an ongoing dispute between the brothers and held Hossein on $1 million bail. The family had hired a private investigator months after Mohammad disappeared, and that work reportedly produced leads used by law enforcement.

Mohammad’s remains have not been found. Does anyone have information about Mohammad’s last known movements in West Hills or about the household situation before May 1, 2008?
