WILMINGTON, Del. (CBS) – Five people were injured in a crash along interstate 95 in Wilmington, Delaware Saturday morning.

The accident happened on I-95 southbound, just north of Silverside Road at about 4:30 a.m.

Police say 19-year-old James McGlaughlin of Chesapeake City, Maryland was driving his 2002 Oldsmobile Alero with four passengers in the left lane of I-95 south.

For an unknown reason, investigators say McGlaughlin’s vehicle swerved off of the west edge of the road and traveled up an embankment. The vehicle then struck several trees before overturning onto its roof.

McGlaughlin was transported to Christiana Hospital where he was treated for non-life threatening injuries. The other four passengers in the vehicle, 19-year-old Danielle Flanigan of Newark, 20-year-old Elicia and 21-year-old Morgan Delk and 20-year-old Melissa Colligan, all of Elkton, Maryland, were taken to Christiana Hospital where they were being treated for serious injuries.

This crash remains under investigation at this time. Alcohol is being considered as a factor. I-95 south was closed for about 1.5 hours as the crash was investigated and cleared.
