‘I’m gonna kill you’: Marine dies after being attacked off California coast

A Marine died Tuesday after he was attacked off the California coast.

The man, who was wearing a life jacket, was attacked about 5 p.m. near the village of Long Beach, according to the Los Angeles Times.

He was rushed to the hospital, where he later died.

His name was not released.

The Marine Corps said it was aware of the attack and has an investigation underway.

The death comes amid rising sea levels that have made coastal cities more susceptible to coastal erosion, which can be deadly.

The U.S. Coast Guard says the average annual increase in sea levels over the past century has been between 0.1 millimeters per year and 0.5 millimeters, and sea level rise is expected to reach as high as 2.5 feet.
