Maine State Police said one man was killed and another critically injured when the driver of a car they were riding in fell asleep and crashed the vehicle on Interstate 95 early Sunday morning in Penobscot County.

A family from Massachusetts was heading south when their 2006 Honda Civic, operated by Sonja Ebron 64, of Milton, Massachusetts, went off the southbound lane of the highway and rolled over several times before coming to rest in the median strip, said Stephen McCausland, spokesman for the Maine Department of Public Safety.

Giovonni Mykell Ebron-Burgess, 23, of Dorchester, Massachusetts, was pronounced dead at the scene by the East Millinocket and Lincoln Ambulance Service crew.

Another passenger, Keon R. Ebron, 27, of Mattapan, Massachusetts, suffered serious injuries and was flown by Life Flight helicopter to Eastern Maine Medical Center in Bangor. He was listed in critical condition there Sunday night.

Sonja Ebron and another passenger, Peta A. Thompson, 19, of Boston, suffered minor injuries. They were both treated and released from Penobscot Valley Hospital in Lincoln.

State Trooper Cooper Plaisted is investigating the accident, which took place at 6:41 a.m. in Township 2, Range 9 near Medway.
