CONCORD, N.H. - Two state prison inmates, including one convicted in a savage murder 1997, are charged with conspiring to sell crack cocaine to other prisoners. Christopher Doucette, 27, Jeremy Slack, 29, and non-prisoner Sarah Stanwood face prison sentences of 10 to 20 years if they are convicted, authorities said Thursday in announcing the indictments. They said the charges stemmed from a lengthy state police investigation that began in September.

In a separate investigation, inmate Michael Gilpatrick Jr., 22, was charged with possessing marijuana with intent to sell, a repeat offense, and delivering unspecified articles to prisoners. He faces 3-to-6 years on the first charge and 3 1/2-to-7 years on the second if convicted.

Another separate investigation led to illegal-delivery charges against a fourth prisoner, 33-year-old Robert Grimes, and non-inmate Wanda Bezio, state police and the attorney general announced.

Doucette, then of Lunenberg, Mass., was 18 when he and two friends brought two teenage girls to a pond in Salem in 1997 and fatally stabbed them. He was sentenced to 37 years to life after being convicted of second-degree murder.

In sentencing one of the other killers, Superior Court Judge Douglas Gray, since retired, called it "the worst case I have sat on in my 15 years on this bench."
