Richard Farnell is recovering in a Reno, Nev., hospital from injuries sustained in Monday's crash of a single-engine plane near the Truckee Tahoe Airport.
His wife, 55-year-old Darla Farnell, was pronounced dead at the scene.
The Orange County Register reported Wednesday (http://bit.ly/1dvhkEI) that the 71-year-old Farnell was a deputy district attorney from 1968 to 1981. He prosecuted Alcala among dozens of other criminals before starting a private practice in Newport Beach.
The Piper PA-46 Malibu took off from Santa Ana's John Wayne Airport. It went down in a rugged area about 6 miles southeast of the Truckee airport.
The cause of the crash is under investigation.
