PHILADELPHIA (CBS/AP) — The engineer behind Amtrak’s deadly 2015 derailment will now face criminal charges.

Pennsylvania Attorney General Josh Shapiro announced Friday evening that Brandon Bostian, the engineer in the derailment that killed eight people and injured nearly 200, has been charged with eight counts of involuntary manslaughter.

Bostian has also been charged with one count of causing or risking a catastrophe and numerous counts of reckless endangerment.

This comes after Philadelphia Municipal Court Judge Marsha Neifield on Thursday ordered the arrest of Bostian on involuntary manslaughter and reckless endangerment charges.

Judge Orders District Attorney’s Office To Reverse Course, Charge Engineer In Deadly Amtrak Derailment

“When the case was sent over to us with just about 24 hours left on the statute of limitations clock, we evaluated the case,” Shapiro told KYW Newsradio. “We looked at all the facts and we decided to charge well beyond what was contained in that private criminal complaint.”

The Philadelphia District Attorney’s Office had announced Tuesday, as the two-year deadline to bring charges loomed Friday, that it couldn’t prove Bostian acted with “conscious disregard” when he accelerated the train to 106 mph on a 50 mph curve.

That judgment call prompted civil lawyers representing the family of a technology executive killed to seek a private citizen’s complaint. They believe Bostian should be held accountable.

Otherwise, veteran lawyer Richard Sprague said, “it’s almost like inviting drivers of vehicles and cars to drive recklessly.”

Federal investigators concluded that Bostian lost track of his location before the May 12, 2015, crash after learning a nearby commuter train had been struck with a rock.

The train had left Philadelphia minutes before, heading toward New York.

“We cannot conclude that the evidence rises to the high level necessary to charge the engineer or anyone else with a criminal offense,” the District Attorney’s Office said Tuesday in an unsigned statement. The current district attorney, Seth Williams, is awaiting trial in a federal bribery indictment.

Amtrak has taken responsibility for the crash and agreed to pay $265 million to settle related claims.

Victims’ Attorney: No Charges To Be Filed In Deadly Amtrak Derailment

It’s rare but not unprecedented for citizens to seek private criminal complaints when they object to a prosecutor’s decision. Pennsylvania judges can approve or reject their petitions, but typically give wide latitude to a prosecutor’s discretion. It’s not clear if any such cases in recent memory in Philadelphia have survived when the prosecutor appealed.

The Amtrak complaint involves only the death of New York executive Rachel Jacobs, 39, who left behind a husband and 2-year-old son. Her father, a Michigan lawyer, had urged Williams to press charges.

“I just feel that my daughter’s death needs to be vindicated. Here is a woman who died and nobody’s being punished,” the father, John Jacobs, told The Associated Press this week. “Somebody should be held responsible.”

The misdemeanor charges each carry a maximum five-year sentence. Bostian’s attorney did not return messages this week seeking comment.
