1965 California plane crash may be solved after underwater researchers discover debris

A 1965 plane crash could be close to being solved after underwater sonar researchers discover debris in Folsom Lake, California.

The drought in California, combined with modern technology, may have uncovered an aviation mystery that has haunted Katherine Radican's family for more than five decades. Researchers at an underwater surveying company said a sonar device they have been testing at Folsom Lake, northeast of Sacramento, picked up what appears to be the debris of a small plane that crashed on New Year's Day in 1965, killing all four people aboard -- including Radican's brother-in-law. Radican, of El Dorado County, told ABC News on Monday that her late husband, Frank Wilcox, spent most of his life searching the 18-square-mile reservoir that straddles three counties for any sign of the long-lost wreckage that claimed the life of his brother, 15-year-old Glen Amick. She said her husband was only 3 years old when his brother, a standout high school athlete, was killed in the sightseeing flight. "He didn't really know his brother, but him and his mom would go out to the lake periodically when the water was low and look around to see if they could see anything," Radican said of her husband, who passed away nearly three years ago.
