FOLSOM (CBS13) — Authorities say the wreckage found in Folsom Lake last week was from a 1986 incident, not the 1965 crash that left four people dead.

A group testing sonar technology found the fully intact plane submerged in 160 feet of water.

The technicians said they were confident the plane matched the description of a Piper Comanche 250 that crashed near Folsom Dam back in 1965. Four people were killed in that crash – and the bodies of three people were never found.

On Wednesday, the Placer County Sheriff’s Office announced that a dive team went back out with the sonar group to get more in-depth images of the plane.

With the new images, investigators have determined that the wreckage was actually from a 1986 incident. In that crash, the sheriff’s office says no fatalities were reported.
