AUBURN — A Lewiston man remained in critical condition Friday night after his minivan slammed into the side of a tractor-trailer on Kittyhawk Avenue the night before.

Police said Abdikadir Mohamed, 43, was driving toward Washington Street at about 6:15 p.m. Thursday when his van plowed into the Hartt Transportation rig.

When rescue crews arrived, Mohamed was unconscious behind the wheel of his vehicle. He was taken to Central Maine Medical Center in Lewiston where he remained Friday night.

It was unknown what caused Mohamed to crash into the side of the tractor-trailer driven by 32-year-old Brian Blanchard of Sabattus.

Blanchard was not hurt.

Because of the severity of Mohamed’s injuries, Auburn police called for assistance from a reconstruction team. The crash remained under investigation.
