At least eight people have died after two smuggling boats capsized near the shore of Black’s Beach in San Diego County, California, officials said.

Authorities responded to the scene Saturday around 11:30 p.m. local time after someone on one of the panga boats, a type of small fishing boat powered by an outboard motor, called 911 to report victims in the water, according to the San Diego Fire-Rescue Department.

The 911 caller, a Spanish-speaking woman, reported two boats had overturned near the Torrey Pines City Beach access route to Black’s Beach, said James Gartland, lifeguard chief for the San Diego Fire-Rescue Department, during a Sunday news conference.

I have been led to believe that the border is so porous, just about anyone can get in.  I wonder why these people would go by sea?
