PLAISTOW — The Plaistow man accused of beating and burning a 3-year-old boy is back in New Hampshire after he and the child’s mother, Jessica Linscott, 23, were arrested at a theme park in Florida.

Roland Dow is now being held at the Rockingham County jail after U.S. Marshals delivered him to the state where he is charged with first- and second-degree assault for allegedly striking Linscott’s son, James Nicholson, in the head on Nov. 1, causing a traumatic brain injury that led to seizures and other symptoms that police say went untreated for weeks. Dow also is accused of burning the boy’s wrist and fingers. Linscott is charged with child endangerment.

U.S. Marshalls contacted Sunday declined to discuss the transportation, but said the agency is responsible for making sure Dow gets to New Hampshire. Dow is listed as an inmate at the Rockingham jail on an online inmate directory. Linscott was returned to New Hampshire on Friday.

The couple fled the state after dropping the boy off at Exeter Hospital on Nov. 14 when the boy suffered several seizures that authorities say were related to abuse. The couple eluded capture until being arrested last week at Universal Studios Theme Park in Orlando, Fla.

Dow faces five additional counts of endangering the welfare of a child while Linscott is charged with six counts of the same charge after they allegedly failed to seek medical treatment for the seizures on several occasions.
