A Maine man expected to testify in the death of a New Hampshire inmate has been charged with robbery, kidnapping, and assault in Maine. Randall Chapman, 37, was arrested by Maine State Police in Gray Wednesday after being on the run since May 19. Chapman is charged with slashing a kidnapped victim’s face during a robbery. Police said Chapman used a woman to lure the victim to an apartment, where he was robbed and forced to drive to an ATM to withdraw money. On the way to the ATM, the victim saw police cruisers in a parking lot, pulled in, and sounded his horn to alert the officers, police said. Chapman bolted. He pleaded not guilty Wednesday to robbery, kidnapping, and aggravated assault, the Sun Journal reported. Chapman was an inmate in a New Hampshire state prison when he agreed to testify against two inmates accused in a 2010 beating of a third inmate who later died.
