A 14-year-old was killed after his raft hit a log and capsized in Eagle River over the weekend, according to Alaska State Troopers.

Around 7 p.m. Sunday, two brothers — identified as 14-year-old Joseph Cantler, of Pennsylvania, and 30-year-old Seth Cantler, of Joint Base Elmendorf-Richardson — were rafting in Eagle River when their boat overturned and they were thrown overboard, troopers wrote in an online dispatch.

Troopers were notified of search efforts in the Eagle River and Cook Inlet confluence area, where the river flows into the Knik Arm, just before 10 p.m..

The JBER Fire Department responded and located Seth Cantler, who was taken to an area hospital, treated and released without injury.

Search efforts for the teen continued through the night and included an air-born search. According to Sgt. Edward Eagerton, the raft was spotted just south of Bravo Bridge.

He was found in the confluence at 2:15 a.m. Monday and pronounced dead at an Anchorage hospital. Trooper spokesperson Timothy DeSpain said Joseph Cantler was wearing a life jacket.

The teen’s next of kin has been notified.

Troopers said no foul play is suspected, but the investigation is ongoing.
