A woman and a second man were also killed when the aircraft slammed into the lagoon near Twin Dolphin Drive shortly before noon on Thursday.

Colleagues identified the other man as 91-year-old Robert Borrman, the founder of R.E. Borrmann’s Steel Co. in East Palo Alto.

On Friday, the San Mateo County coroner’s office identified the woman as 57-year-old Daly City resident Adeline Urbina-Suarez.

Investigators from the National Transportation Safety Board are still working to determine what caused the plane, a Beech 65 Queen Air, to crash into the lagoon.

After taking off from the nearby San Carlos Airport, the pilot had been in communication with air traffic controllers and apparently planned a left-turn maneuver. According to witness statements, the plane traveled to the right before plummeting into the lagoon.

The plane’s remnants were pulled from the lagoon on Friday, sliced into transportable pieces and shipped to a facility in Sacramento where NTSB investigators will study the wreckage.

An initial report on the crash is expected to be released on the NTSB’s website by early next week, but a final report will require six to nine months for completion.
