A 7-year-old boy was killed in a hit-and-run while waiting for the school bus in Franklin Township, Pennsylvania, on Thursday morning.
The motorist who struck the boy apparently did not realize they had hit him and kept on driving, police told ABC News. Their name was not released.
A school bus driver found the boy's body, Tyrone Area School District Superintendent Cathy Harlow wrote on Facebook. The bus driver then called 911 and waited for first responders to arrive.
"Our school community is truly grieved by this terrible loss," Harlow added. "Please keep the family in your thoughts and prayers."
Further details were not immediately released, but the boy's death comes just after three siblings were killed in rural Indiana while crossing the street to board the school bus.
Alivia Stahl, 9, and her brothers, Xzavier and Mason Ingle, died Tuesday morning. The siblings' uncle, Elgin Ingle, said it appeared as though Alivia had tried to step in front of the boys to protect them.
"It's horrible that this happened," Ingle said. "They were holding hands every day on the way to the bus stop, including today … it looks like Alivia stepped in front of the car for the boys."
In that case, the driver of the car that hit them, 24-year-old Alyssa Shepherd, was arrested and charged with three counts of reckless homicide as well as a misdemeanor for passing a stopped school bus. She has been released on $15,000 bond and has not yet entered a plea.
These weren't the only incidents involving children waiting for a school bus this week. On Wednesday, a 9-year-old Tupelo, Mississippi, boy died after being hit by a truck while trying to board a school bus. And seven people, including five children, were taken to the hospital on Thursday in Tampa, Florida, after a car hit people at a school bus stop. None of those injuries are life-threatening.
From 2006 to 2015, 102 people 18 and younger died in school transportation-related incidents. Sixty-four percent of those were hit by school buses or vehicles functioning as school buses, while 36 percent were struck by other cars, according to data compiled by the National Highway Traffic Safety Administration.
