A top prosecutor on Friday charged the speeding Amtrak engineer with causing a catastrophe, involuntary manslaughter and other crimes in a 2015 derailment that came after he accelerated to 106 mph on a 50 mph curve.
Prosecutors said they were in talks with engineer Brandon Bostian's attorney to have him surrender on the charges.
The derailment killed eight people and injured about 200 others.
Pennsylvania Attorney General Josh Shapiro expanded on charges a Philadelphia judge approved a day earlier after the family of a woman killed in the crash sought a private criminal complaint.
The judge ordered city prosecutors to charge Bostian with two misdemeanors over Rachel Jacobs' death in the May 12, 2015, derailment. Shapiro added the felony charge of risking or causing a catastrophe along with seven additional counts of involuntary manslaughter.
