San Mateo – Tuesday the San Mateo County Coroner’s office identified the last of three people killed when a twin-engine plane slammed into a Redwood Shores lagoon.

The coroner’s office confirmed that 91-year-old Belmont resident Robert Borrmann as the third victim killed in the Sept. 2 accident. Friends and colleagues of Borrmann, founder of R.E. Borrmann’s Steel Co. in East Palo Alto, said last week he was among the victims.

Adelina Urbina-Suarez, 47, of Daly City, and William Heinicke, 73, of San Francisco, were identified over the weekend as the other victims.

Borrmann’s 1961 Beechcraft Queen Air crashed into the lagoon just north of Twin Dolphin Drive at about noon on Sept. 2, less than a minute after taking off from nearby San Carlos Airport. It had reached an altitude of 650 feet, and all of its flight controls appeared to be in the correct place, according to an investigator with the National Transportation Safety Board. However, it is not yet clear who was piloting the plane, which had two sets of controls.

A final report on the cause of the crash is expected to take six to nine months.

Crews spent several hours Friday raising the wreckage from the lagoon bottom with air bags, then using a large crane to hoist it onto land.

Recovery efforts had been hampered by contamination caused by a 48,000-gallon sewage spill in the lagoon last month, as well as a small amount of fuel leaking from the aircraft.
