MONTICELLO, Ind. (WLFI)—Around 9 p.m., Monticello Fire Department Water Rescue and Paramedics responded to a report of a speedboat carrying six people Saturday night that struck a large tree limb while traveling on Lake Shafer.

The serious accident happened on the North end of Lake Shafer near the intersection of West Shafer Dr. and County Rd. 800 North.

According to the Indiana Department of Natural Resources, Boat-operator Jason Ward, passengers James Scott and John Mahoney III were removed from the boat by rescue crews on the scene and were taken by Monticello Fire Department Paramedics to IU White Hospital.

Both Scott and Ward were airlifted to IU Methodist Hospital in Indianapolis around 9:30 p.m. with critical life-threatening injuries. The details of their injuries have yet to be released.

Mahoney was also treated and transported to IU White Hospital with what claimed to be non-life threatening injuries.
