Two New York men face manslaughter and other charges in the deaths of two young brothers under their watch who fell over a 70-foot waterfall.

Wyoming County District Attorney Donald O'Geen tells the Rochester Democrat & Chronicle (http://on.rocne.ws/2frkMoC ) that the deaths were not only tragic but also "100 percent preventable."

The prosecutor says 32-year-old Chad Staley and 34-year-old Tyler Jennings were with a group of boys that left a designated trail at Letchworth State Park in Castile in June. They had gone into the water to get a better view of the falls when the two boys were washed away.

Six-year-old Preston Giangregorio and his 9-year-old brother, Dylan, were killed.

Staley and Jennings were indicted Tuesday on manslaughter and criminally negligent homicide charges. It's unclear if they have attorneys.
