The combination of two teen boys in a kayak and an oncoming thunderstorm that churned a Pa. creek proved deadly.

As the Morning Call of Allentown reports, it happened Wednesday night in Bucks County, Pa., where one of the teens fell out of the kayak and into the rain-swollen Mill Creek.

A 16-year-old Bucks County boy who was not identified in initial reports got caught up in the churning creek and was under the water for about five minutes before being rescued by a firefighter, the newspaper reports.

The Penndel Rescue Squad was able to get a pulse on the boy after he went into cardiac arrest, Middletown Township police Lt. John Michniewicz told the Morning Call.

The boy was first taken to St. Mary Medical Center nearby, before being transferred to The Children’s Hospital of Philadelphia.

But the boy died there early Thursday morning.

The boy, from Penndel, Pa., was kayaking with a 17-year-old boy in Mill Creek in the Snowball Gate section of Levittown around 8:30 p.m. Wednesday when he fell out of the kayak during a thunderstorm, beginning the deadly chain of events, the Morning Call reports.
