A 16-year-old Salinas boy died Sunday afternoon after leaping off a rock cliff near the bank of the Stanislaus River about a mile east of the Parrotts Ferry Bridge, authorities said.
It's not known if Aaron Tyler drowned or suffered fatal injuries from the jump, estimated at about 75 feet, according to Sgt. Jeff Wilson of the Tuolumne County Sheriff's Department.
An autopsy was scheduled to be done Monday.
Wilson said Aaron was vacationing with another family. Wilson said he believed the family accessed the rock cliff from a boat. Some in the party climbed the rock cliff and jumped into the river.
Aaron did not surface after he jumped. After a short search by those on the boat, emergency crews were called about 3 p.m.
Divers with the Calaveras County Sheriff's Department, along with the search and rescue team from the Tuolumne County Sheriff's Department, tried to find Aaron.
His body was discovered about 8:30 p.m., Wilson said.
Wilson said he didn't know the specifics of Sunday's fatal jump but that rock or cliff jumping into water is a fairly common activity in the foothills.
It's one that should be avoided, he warned. Shallow water, the inability to jump out far enough and immersed tree stumps can be fatal to unsuspecting jumpers.
"Just hitting the water at the wrong angle can kill you," Wilson said.
