ROCHESTER – The four-day jury trial for Alyssa Shepherd, accused of hitting four children and killing three as they boarded a school bus in October last year, will begin Tuesday in Fulton County Superior Court.

Judge Greg Heller will preside over the case and jury selection will begin Tuesday morning.

Shepherd, 24, faces three charges of reckless homicide, Level 5 felonies; passing a school bus with the arm extended where bodily injury results, a Class A misdemeanor; and criminal recklessness committing aggressive driving resulting in serious bodily injury, a Level 6 felony.

If convicted on all charges, Shepherd faces a maximum sentence of 211⁄2 years in prison.

The crash happened around 7:15 a.m. Oct. 30 when Shepherd allegedly hit and killed 9-year-old Alivia Stahl, her 6-year-old twin brothers Mason and Xzavier Ingle, and severely injured 11-year-old Maverik Lowe.

The children were crossing Ind. 25 north of Rochester to get on their school bus when they were struck. The bus’s flashing lights were on and its stop arm was extended.

Shepherd told police she did not recognize the vehicle as a school bus.

Shepherd is represented by attorneys David William Newman and Michael Joseph Tuszynski, of Stanley Tuszynski & Newman, South Bend.

The incident caught national attention and prompted legislation to be passed in Indiana in April named after the children called the MAXSTRONG bill. The bill mandated safety changes that include requiring stop-arm cameras on buses, no longer allowing children to cross state highways to board a bus and increasing penalties for those who disregard the law.

The parents of the children, Michael Stahl and Brittany and Shane Ingle, have celebrated the legislation named after their children saying their children did not die in vain.

Media credentials at Tuesday’s court proceedings were limited to four. The Times-Union will be covering the trial.
