Authorities say one person has died after a boat packed with suspected illegal immigrants overturned off the San Diego coast.

Customs and Border Protection spokesperson Jackie Dizdul says 23 people were believed to be on the 30-foot boat when it overturned in the surf at Torrey Pines State Park around 4:30 a.m. Saturday.

Dizdul says one person died on the way to the hospital. Five others were hospitalized, including at least one in critical condition.

Nine others are in Border Patrol custody and eight are not accounted for. The park is closed for a search.

Coast Guard Lt. Josh Nelson says his agency has dispatched two boats and a helicopter to search for anyone who might still be in the 58-degree Fahrenheit waters.
