ROCHESTER, Ind. (WPTA21) – Multiple charges were filed late Tuesday afternoon in connection with an accident that killed three Indiana school children and injured a fourth.

Officials in Fulton County filed the charges against 24-year-old Alyssa Shepherd of Rochester. She faces three counts of reckless homicide and one count of passing a school bus with its safety arm extended and causing injury.

Shepherd was allegedly behind the wheel of a pickup truck that struck the children as they were boarding a school bus in Fulton County, Ind., Tuesday morning.

State Police identified the three young siblings who died as 6-year-old twin brothers Xzavier and Mason Ingle and their 9-year-old sister, Alivia Stahl. All three were students at Mentone Elementary School.

The siblings and an unrelated 11-year-old boy were struck about 7 a.m. as they were crossing a two-lane road near Rochester, about an hour-and-20-minute drive west of Fort Wayne, to board a Tippecanoe Valley School Corp. bus.

Slocum says the injured boy, Maverik Lowe, is undergoing surgery at a Fort Wayne hospital.

ABC21 reporter Kaitlyn Kendall spoke with the uncle of the three children who were killed, a man who expressed the heartbreak of the entire family.

“He lost all of his kids,” a distraught Elgin Ingle said of his brother. “How do you tell your little brother it’s going to get better? You can’t.

“My brother — the most loving man in the world and the best father I’ve ever known. And now he’s a father to no one.”

Sgt. Tony Slocum with Indiana State Police described it as one of the most difficult days in his long career.

“This was a very tough scene,” he said. “Almost 20 years as a police officer, it’s going to be one that I always remember.”
