A 27-year-old San Francisco man was identified by family as one of the four people who were believed to be killed in a small plane crash near Half Moon Bay.

The family of Isaac Zimmern told the San Francisco Chronicle on Friday that he was on the plane with his longtime partner, Emma Willmer-Shiles, and another couple when it crashed around 7 p.m. on Jan. 14.

The family asked both the public and media to respect their privacy and did not release any other information, the newspaper reported. The Standard was unable to reach Zimmern's family on Friday night.

The San Mateo County Coroner's Office identified Willmer-Shiles, who went by Pearl, on Tuesday after her body was found in the water near the crash site. The other occupants have not been found, and search and rescue efforts were called off on Monday.

The National Transportation Safety Board said there were four individuals on board the Cozy Mark IV, a four-seat light aircraft constructed from a kit, when it crashed. The NTSB is leading the investigation into the incident.
