SLO Sheriff Arrests Two Brothers for Homicide in Missing Woman Investigation

The San Luis Obispo County Sheriff’s Office has provided an update and made two arrests in their investigation of a Coalinga woman that’s been missing since September 12.

Isabel LucasVelasco, age 50, was last known to be in San Luis Obispo County on September 12, 2025 and has ties to the City of Coalinga and the City of Visalia. Last month the Sheriff’s Office Detective Division issued a missing person’s statement and said they are currently investigating her disappearance under suspicious circumstances.

Earlier this month, the Sheriff’s Office announced they had identified and seized two vehicles for evidence. Now the Sheriff’s Office is announcing two arrests in the case and a clear timeline of LucasVelasco’s disappearance.

LucasVelasco was reported missing to the Sheriff’s Office on September 13th. During an initial investigation, the Sheriff’s Office determined she was last seen at a job site in rural Arroyo Grande on September 12th.

On Saturday, October 11th, the San Luis Obispo County Sheriff’s Office and the Fresno County Sheriff’s Office Search and Rescue teams, along with detectives, conducted an extensive search of Highway 198, west of Coalinga.

During this search, Search and Rescue located a body, believed to be LucasVelasco. The body has been turned over to the San Luis Obispo County Sheriff’s Coroner Office for confirmation of identification.

This case is now considered a homicide, and two people have been arrested in connection to this incident. Alejandro SorianoOrtiz, 45, of Coalinga has been arrested for one count of murder and one count of arson, in connection with burning the victim’s vehicle. His brother, Celestino SorianoOrtiz, 40, of Santa Maria has been arrested as an accessory to murder, as well as for the arson incident.

“We want to thank the Fresno County Sheriff’s Office and the San Luis Obispo County District Attorney’s Office for their valuable assistance,” Sheriff Parkinson said. ” I also want to highlight the amazing work of our Sheriff’s Office Major Crimes Unit (MCU), Special Victim’s Unit (SVU), Special Operations Unit (SOU), and the Sheriff’s Search and Rescue Unit for their tireless dedication to solving this case and giving some closure to Isabel’s family.”

Alejandro SorianoOrtiz is believed to be the former boyfriend of LucasVelasco. This case is still under active investigation, and no further information or comment is available at this time.
