605 Freeway closed in Seal Beach following fatal multi-vehicle collision

One person was dead following a multi-vehicle collision on the 605 Freeway in Seal Beach Monday morning.

The cause of the crash, which occurred just before 3:40 a.m., was not immediately known, but California Highway Patrol officials had issued a Sigalert for all lanes of the southbound 605 Freeway and southbound 405 Freeway connector in Seal Beach as a result. 

One woman was killed in the accident. She was behind the wheel of a Nissan Murano.

"For reasons still under investigation, the Nissan veered to the left into the center median, where it collided head-on with an attenuator barrier, causing the Nissan to come to rest facing wrong way within the HOV lane," said California Highway Patrol Officer J. Cerda. 

The Nissan was then struck by an oncoming Honda Accord, killing the woman.

Late Monday evening, the woman was identified as 24-year-old Jakayah Lassiter.

Two other men, aged 70 and 32, sustained injuries and were rushed to nearby trauma centers for treatment.

As traffic continued to backup, CHP also issued a Sigalert for southbound 605 lanes from Willow Avenue in Long Beach.

At around 4:30 a.m., the far right lane was opened to traffic.

All lanes have since reopened.
