A Skowhegan man on Thursday denied charges stemming from a police chase that ended in Winthrop when the fleeing driver crashed a car into an SUV driven by a pregnant woman.

Glen Witham, 39, entered his pleas in Androscoggin County Superior Court via video link from a state prison. He pleaded not guilty to charges of aggravated assault, reckless conduct, eluding an officer, theft by deception and passing a roadblock.

Most of the charges are related to the May 12 crash in which police say the car Witham was driving slammed into an SUV driven by a 27-year-old woman who was eight months pregnant.

The car Witham was driving flipped off the road. The woman escaped without life-threatening injuries. Witham was hospitalized for a time in critical condition.

The day of the car crash, Witham’s legal problems were mounting.

He had been told to report to Androscoggin County Jail within 72 hours of an unsuccessful appeal on an unrelated crime. When he didn’t show up, a warrant for his arrest was issued.

Meanwhile, a deputy at the Androscoggin County Sheriff’s Department was investigating stolen laptop computers. Deputy Maurice Drouin suspected Witham committed the thefts and arranged to meet with him during an online correspondence.

Witham had allegedly bought computers at local stores and billed an acquaintance at an address different from his own. One of the computer sellers helped pinpoint its whereabouts through tracking software built into the device.

Witham had posted for sale an item on Craigslist, a popular website for classified advertising. Drouin set up a meeting in May with Witham to discuss the purchase of the item. It appears Witham was spooked and drove off as Drouin approached.

Beginning in Greene, Witham raced up Route 202 through Monmouth into Winthrop in a Dodge Stratus, according to Androscoggin County Sheriff Guy Desjardins.

Witham managed to avoid spike mats at two roadblocks before the chase came to a violent end.

Witham was allowed to enter his plea through video because he is in a wheelchair and mobility is a problem. He was sentenced last year to two years in prison, with one year suspended, on a charge of theft by unauthorized taking.
