The Coast Guard said watchstanders at the Joint Harbor Operations Center in San Diego were initially informed of the crash around 12:45 p.m. on Sunday, June 8. The search was suspended at 10 a.m. local time on Tuesday.

Six people were killed when a small plane crashed into the ocean off San Diego on Sunday afternoon, the Federal Aviation Administration said Monday.
