A Grand Forks man convicted of killing a woman 21 years ago will be allowed to transition to a halfway house starting in February 2016. The North Dakota Parole Board granted the move on behalf of Alvin Englehart. Englehart was sentenced to 38 years in the North Dakota State Penitentiary in connection with the 1991 death of Shirley Stigal. Stigal was found strangled in her Grand Forks apartment on North Seventh Street. Englehart was arrested two months later in Texas when he failed to pay a restaurant tab. Under the board’s directive Englehart will spend nine months in a half-way house or until November 2016 -- the same date that he would have been eligible to be released from prison.
