Officials said Maryland Transportation Authority Police tried to stop a Chevrolet Silverado on Sunday morning on Interstate 95 north of the Fort McHenry Tunnel in the Baltimore area. Authorities say the Laconia, N.H., police reported the truck stolen Friday.
The driver failed to stop, leading police on a pursuit for about 50 miles into northeastern Maryland.
The pursuit ended when the driver of the Chevrolet, 28-year-old Stephen Reinholz of Laconia, lost control. The truck struck a guard rail and went down an embankment.
Reinholz and a passenger, 28-year-old Kaili Pierce of Concord, N.H., died at the scene, officials said.
Also, a pileup on the Florida Turnpike Sunday evening killed two people.
Police identified the victims as a 20-year-old woman and a 19-year-old man who were traveling in the same vehicle, which was struck from behind.
The seven-vehicle crash occurred near Howey in the Hall, northwest of Orlando. Police said nine people were taken to hospitals after the pileup.
Traffic was backed up for 10 miles in the northbound lanes after the accident, according to the Department of Transportation.
