Jessica Linscott, Roland Dow Remain on the Run

A Plaistow couple charged with remain on the run from police.

Police have received tips that Jessica Linscott, 23—the mother of the boy—and her boyfriend, Roland Dow, 27, were recently at gas stations and coffee shops in the North Shore part of Massachusetts. There was a possible sighting Monday in Lowell.

A police report Sunday said they may be trying to make their way to Maine in blue Dodge minivan with a New Hampshire license plate numbered 2844129.

Rockingham County Attorney Jim Reams said Monday police are receiving more and more tips on their whereabouts.

MyFoxBoston.com reported Monday that Linscott may have dyed her hair black while on the run.

Dow is charged with first- and second-degree assault for allegedly hitting the child in the head and burning his fingers and wrist.

The boy, James, reportedly suffered a head injury that impaired his vision. 

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

James is in now stable condition at Dartmouth Hitchcock Medical Center in Lebanon, NH.

Reams has demanded that Dow and Linscott turn themselves in.

"No matter where you go, (police) are going to find you," Reams said at a recent news conference. "Surrender yourselves."

Linscott is charged with child endangement.

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.

The 3-year-old's grandmother is Helen Nicholson, of Melrose, Mass. She told WMUR.com that she's "frantic."

"They both need to pay for this and they need to pay big. This is not a small case," Nicholson told WMUR. "They tried to kill my grandson."
