Newport — Former Claremont resident Wayne Keough was sentenced in Sullivan County Superior Court on Wednesday to up to 15 years in New Hampshire State Prison for his part in a 2017 armed robbery.

Keough, 40, pleaded guilty to two felony charges of robbery armed with a deadly weapon and reckless conduct with a deadly weapon, according to a press release from the Sullivan County Attorney’s Office. The charges came as a result of Keough’s robbery of a car from the Claremont Walmart parking lot in April 2017. Keough forced the car’s owner from his car at knifepoint.

Keough fled the scene of the robbery. Days later, he led Claremont police on a high-speed chase, reaching speeds of 80 miles per hour, before entering Vermont.

In addition to the 7½- to 15-year sentence for the armed robbery charge, Keough was sentenced to a 3½- to 7-year suspended sentence on the charge of reckless conduct with a deadly weapon. The suspension is contingent on good behavior.
