A Castaic man quietly walked into a local sheriff’s station on Thursday and was arrested in connection with a fatal hit-and-run that killed a pedestrian in Valencia earlier this month. Deputies said the collision happened on April 10 near Magic Mountain Parkway and Tourney Road, and that the driver took off instead of stopping. The man, identified locally as a 67-year-old Castaic resident, surrendered at the Santa Clarita Valley Sheriff’s Station and was booked into custody.
Crash and victim
Deputies were called around 8:22 p.m. on April 10 to reports of a person hit by a vehicle at Magic Mountain Parkway and Tourney Road. The Los Angeles County Medical Examiner later identified the victim as 39-year-old Dion Mumphery and listed his cause of death as traumatic blunt force injuries. Los Angeles County Fire Department personnel pronounced him dead at the scene, according to MyNewsLA.
Arrest and custody records
An official at the Santa Clarita Valley Sheriff’s Station confirmed the suspect turned himself in Thursday morning at the station jail on Golden Valley Road, according to the Santa Clarita Valley Signal. The paper reported that LASD custody records show he was arrested at about 10:15 a.m., booked at 11:02 a.m. and released by 2:15 p.m. Station officials identified the suspect as 67-year-old Brian Foraker of Castaic.
What witnesses reported
Deputies said the vehicle that hit the pedestrian kept going westbound on Magic Mountain Parkway after the crash, and initial reports described it as a large, dark-colored pickup. One witness told investigators it appeared to be a Ford F-150, the Santa Clarita Valley Signal reported.
Justin Yang, a spokesperson for the Los Angeles County Fire Department, said crews found the victim in grave condition when they arrived. "Units arrived on scene to find a patient on the floor, pulseless and apneic," he told reporters. Those early details were carried in local coverage such as KHTS.
Investigation and leads
The same account in the Santa Clarita Valley Signal noted that anyone with information about the truck, the driver or the crash is asked to contact Detective Cramer at 661-260-4000 ext. 5678. The Los Angeles County District Attorney's office told local reporters it did not have filing information as of the time of that report. Authorities said the investigation remains active as detectives review evidence and follow up on witness statements.
Legal stakes
Leaving the scene of a crash that results in injury or death can be prosecuted under California Vehicle Code section 20001, which allows for felony hit-and-run charges and potential prison time in serious cases. The statute and its penalties are summarized in state code listings such as Justia.
Local authorities are asking anyone who saw the collision or has video of the incident to contact the Santa Clarita Valley Sheriff’s Station. As reported by MyNewsLA, investigators are continuing to gather evidence and follow leads in the case.
