CRESCENT CITY — An explosion occurred on July 5 at the Point St. George beach parking lot in Crescent City, Del Norte County, California. A man sustained injuries after an explosive device detonated as he walked along the beach.

The Del Norte County Sheriff's Office stated the man was transported by Del Norte Ambulance to Sutter Coast Hospital. Authorities launched an investigation into the cause of the explosion and searched the nearby beach for additional explosive devices. The sheriff's office did not officially identify the injured man or state the type of explosive device that detonated.

An online fundraiser created by the man's family identifies him as Jason. The family stated Jason was walking along the beach with his girlfriend, Pamala, picking up discarded fireworks and other trash at the time of the incident. The family indicated Jason picked up a "bomb-like device" that unexpectedly exploded.

The blast resulted in the amputation of Jason's hand, according to his family. He is also receiving treatment for vision and hearing injuries and is expected to undergo additional surgeries. Jason was transported to UC Davis hospital in Sacramento for further treatment of his injuries.

Ashley Turner is the victim's daughter. Pamala, Jason's girlfriend, witnessed the explosion. She told CBS News Sacramento, "I used my shirt as a tourniquet to help stop the bleeding until first responders arrived."

The Del Norte County Sheriff's Office asked anyone with information about the incident to contact investigators. Officials reminded the public not to touch any suspected explosive devices. The sheriff's office stated that anyone who discovers a suspicious item should move to a safe distance and immediately contact law enforcement.
