VAN NUYS (CBSLA.com) — A Glendale resident has turned himself in to police after being served a warrant in connection with a deadly car accident in Valley Village, authorities reported.

In August, Arman Samsonian was allegedly speeding on Magnolia Boulevard when his car sheared off the top of a fire hydrant and plowed into a concrete light pole, creating a pool of electrified water.

Two good Samaritans, 40-year-old Irma Zamora of Burbank and 39-year-old Stacey Lee Schreiber of Valley Village, were killed when they stepped into the water to try and help Samsonian.

Several others were injured — including a police officer — when they responded to the scene.

An investigation by the LAPD traffic division ruled out drugs and alcohol playing a part in the collision, but did reveal Samsonian was allegedly speeding. Back in August, officers said Samsonian was going 50 in a 35-mph zone.

The 19-year-old suspect was jailed in Van Nuys Thursday on two counts of felony vehicular manslaughter, police reported.

He is currently free on bail and will make his next court appearance on Nov. 9 in Van Nuys.

Authorities have not said whether Samsonian has any prior criminal record.
