BOSTON (CBS) – A New Hampshire mother will testify against the man accused of beating her three-year-old son.

Last year, police found Jessica Linscott and Roland Dow hiding out at Universal Studios in Florida. They were under investigation for the severe beating of three-year-old James Nicholson.

According to the New Hampshire Union Leader, Linscott will become a state witness against Dow. His trial is scheduled for next month.

Dow is accused of striking the boy in the head causing a traumatic brain injury, and burning the boy’s wrist and fingers.
