Maine State Police are investigating a fatal crash that happened on the southbound Maine Turnpike near mile marker 20 in Wells Friday morning.

Police said four cars were involved in the crash just before 9 a.m. The pileup began when a Toyota Prius driven by Oguzhan Cildir, a 23-year-old from Brighton, Massachusetts, struck a Toyota pickup operated by Gloria Cascio, 53, of Albion, police said. Her car rolled several times and Cascio was pronounced dead at the scene.

Vincent Cascio, 60, of Albion, was a passenger in the pickup and was transported to Maine Medical Center with life-threatening injuries. Another driver involved in the crash, Troy Perrault, 51, of Old Orchard Beach, sustained minor injuries.

The crash brought southbound traffic to a standstill Friday morning. The lanes were reopened early Friday afternoon.

State police said in a post around 10 a.m. on X, formerly known as Twitter, that there was a significant multivehicle crash at mile marker 20, just above Exit 19. Traffic was diverted to Exit 25 in Kennebunk.

The Maine Turnpike Authority also issued an alert Friday morning just before 9 a.m., notifying people of the crash and saying to expect delays and use caution in the area.
