It was announced on Tuesday by the National Transportation Safety Board that in light of the coronavirus pandemic it has decided to cancel an April meeting to determine the probable cause of a 2018 crash that killed three siblings crossing a rural northern Indiana highway to reach their stopped school bus.

The federal agency said that in place of the April 7 meeting in Washington, D.C., NTSB board members will use an online link to vote on the staff’s investigative report, which contains the crash’s probable cause, findings and safety recommendations. The date of the board’s online vote has not been scheduled.

The crash in question is involves an October 30th, 2018, crash involving a pickup truck on two-lane Indiana 25 in Rochester, that killed 6-year-old twin brothers Xzavier and Mason Ingle, and their 9-year-old sister, Alivia Stahl. A fourth child, Maverik Lowe, 11, suffered critical injuries.

Alyssa Shepherd, age 25 of Rochester was convicted in October of reckless homicide, criminal recklessness and passing a school bus, causing injury. She was sentenced to four years in prison although she is appealing her convictions.

Authorities have said the students were waiting for the bus on the opposite side of the road. The school bus’ red warning lights were active, and its stop arm was extended. After being signaled by the driver to cross, the four students entered the roadway and were struck by Shepherd’s truck.
