CBS News reports that three children were killed by a driver at an Indiana school bus stop yesterday. In Rochester, a 9-year-old girl and her twin 6-year-old brothers were hit and killed by a truck while crossing the road to get on the school bus before sunrise. Another child was hurt in the accident and airlifted to the hospital.

Robert Reid, 46, was driving the school bus when he lowered the stop-arm at about 7:15 a.m. and a Toyota Tacoma ran over the children while they were trying to cross and board the bus. No children were on the bus when the accident occurred. The three victims died at the scene of the accident, while the fourth suffered broken bones and went into surgery in Fort Wayne, Indiana.

The driver of the Tacoma, Alyssa Shepherd, 24, was arrested and charged with three counts of reckless homicide and one count of passing a school bus illegally, causing bodily harm. The first three counts are felonies and the fourth is a misdemeanor. Shepherd was arrested at her place of work and had a bond set at $15,000.

In Indiana, it is state law to stop when a school bus is picking up or dropping off children. The victims in this case had the right of way. The Tippecanoe Valley School Corporation has dispatched counselors to aid students, parents and staff to the schools in the area.
