At least one person is dead, and 10 others hospitalized after what’s being described by authorities as a 48-foot-pleasure craft with 11 passengers aboard crashed in the waters off Long Beach Wednesday night.  

Crews with the Long Beach Fire Department responded to the area of the Los Alamitos Bay jetty just before 9:30 p.m. on reports that a vessel had run into the rocks, overturned and began taking on water, Long Beach fire officials confirmed to KTLA.  

When first responders arrived at the scene, it was determined to be a mass casualty incident.  

Aerial footage of the incident captured by Sky5 showed a heavy presence of first responders as victims were rescued and loaded aboard ambulances bound for nearby hospitals.  

The details of the crash are extremely limited and it’s unclear exactly what caused the vessel to hit the rocks, but authorities told KTLA that speed was likely a factor and that one victim, only described as 40-50 years old, was declared dead aboard the ship.

Five other passengers required physical rescue, authorities added.

A total of 10 patients were rushed to the hospital, seven in stable condition and three in critical condition.

No further details were immediately available.
