CASCO — Authorities in Cumberland County continued their investigation Sunday into an early morning crash that killed a man and boy after the driver of the vehicle they were riding in tried to evade police.

Thomas St. Saviour, 29, of Hiram and a 14-year-old boy from Baldwin were both killed in the 1:14 a.m. accident on Route 11, also known as Poland Spring Road, in Casco. The two were passengers in a 1993 Infinity driven by Nicholas Sparrow, 20, of Casco.The vehicle belongs to Sparrow’s girlfriend, who was not in the car at the time of the crash.

According to a statement issued by the Cumberland County Sheriff’s Office, a deputy attempted to pull Sparrow over for speeding and driving without headlights on Route 11 just minutes before the crash. Sparrow was traveling from the area of Route 302 and initially pulled over after about a mile, but then took off at a high rate of speed.

The deputy lost sight Sparrow but came upon the car about two miles down Route 11, where it had crashed into a stand of trees just off the roadway in an area known as Rye Field Flats.

St. Saviour and the 14-year-old boy were pronounced dead at the scene. Sparrow was transported by LifeFlight to Central Maine Medical Center. No information was available about his condition Sunday night, according to a nursing supervisor at the hospital.

Fire and rescue crews from both Casco and Naples responded to the scene Sunday morning.

The accident remains under investigation and is being reconstructed by authorities. No charges had been filed as of Sunday night.
