OCEANO, Calif. -

The SLO County Sheriff's Office has tentatively identified the pilot in Tuesday's fatal plane crash off Oceano as David Brian Casey of Friday Harbor, Washington.

Based on information gathered during the course of the investigation and the discovery of a wallet at the crash site, sheriff's officials believe the 63-year-old man was piloting the plane. Investigators are trying to determine if there was a passenger on board at the time of the crash.

The Federal Aviation Administration said the plane that went down was an amateur-built, kit model airplane and was co-owned by the man believed to be the pilot, and somebody else by the same last name, Timothy J. Casey.

Members of the San Luis Obispo County Sheriff's Department Dive Team spent the better part of Wednesday in the ocean off Oceano, searching for debris and remains.

The search area includes an area offshore near Pier Avenue and the Oceano Dunes.

On Tuesday evening, the U.S. Coast Guard reported results of the first search which included some human remains, a wallet and small pieces of wreckage.

Emergency crews were called to the scene after 2:00 p.m. on Tuesday when witnesses nearby heard a plane with engine problems and then saw a large splash of water as the plane dropped into the ocean.

Local airports have not reported any missing aircraft or flights.

Once the wreckage was located, the incident was turned over to investigators from the Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB).

This story will be updated throughout the day as new details are made available.  Complete details will be provided tonight on KCOY Central Coast News and KEYT NewsChannel 3 at 5:00 and 6:00.
