Updated: Roland Dow and Jessica Linscott Still on the Run

A New Hampshire mother and her boyfriend accused of inflicting horrific injuries on the woman's 3-year-old son continued to avoid capture Wednesday.

But on Wednesday night Lynn police issued an alert that the couple might be riding in a red, late-90s Volvo with green bumper stickers and a luggage rack, according to NECN. 

They were reportedly seen at Honey Dew Donuts on Western Avenue in Lynn.

Jessica Linscott, 27, and Roland Dow, 23, both of Plaistow, are the target of a manhunt stretching from New Hampshire to Massachusetts. Police said Dow hit the child in the head and burned his wrist and fingers. He was charged with assault and several counts of child endangerment. Linscott was also charged with several counts of child endangerment.

Police said they discovered the boy's injuries after he was treated at Exeter Hospital last week.

The boy is currently in stable condition, said Rockingham County Attorney Jim Reams.

The head injuries reportedly impaired the vision of the child, who was being cared for at Dartmouth Hitchcock Medical Center in Lebanon, NH.

Reams demanded that Dow and Linscott turn themselves in.

"No matter where you go, (police) are going to find you," Reams said at a news conference at Rockingham County Superior Court in Brentwood Wednesday. "Surrender yourselves."

Reams said the pair are likely traveling in a car and may have people helping them avoid capture. He said he has no reason to believe Dow is holding Linscott against her will.

Police said the pair may have been seen in Swampscott on Tuesday.

Swampscott police Det. Tim Cassidy said on Tuesday that he would be in touch with Plaistow police.

Cassidy asks that if anyone sees the couple in Swampscott that they report it to police at 781-595-1111. If they are seen in traffic it is helpful to note the plate number and the location of the vehicle.

People can report it anonymously through the department's mobile tip line.

The Manchester (NH) Union Leader reported that the 3-year-old's grandmother, Helen Nicholson, of Melrose, Mass., does not think authorities will find the couple. 

Nicholson said her son, who died two years ago, was the boy's father. She also told the newspaper that Linscott and Dow "have been dating for about a year and that James was often left with her or Linscott's mother."

Anyone with information on the couple's whereabouts is asked to call Plaistow police at 603-382-6816.
