CONCORD - Two state prisoners and a Laconia woman are under indictment, accused in a drug-smuggling ring in which Suboxone was hidden under the adhesive flaps of mail delivered to the New Hampshire State Prison for Men.

Nathan Morton, 33, who is serving a sentence for possessing heroin, was indicted by a Merrimack County grand jury on six counts of conspiracy to commit the crime of delivery of articles to prisoners.

Shawn Stayrook, 29, who is serving a sentence for numerous burglaries, was indicted on one count, while Kimmel Norwood, 37, of 22 Strafford St., Apt. 305, Laconia, was indicted on six counts.

According to the indictments handed up Feb. 14 and released Wednesday, Morton asked Norwood to mail him Buprenorphine, commonly known as Suboxone, told her how to conceal the drugs, and instructed her not to use a return address.

On Aug. 6, 2012, Morton asked her, "You know that thing, can you do that today?" and then the next day, asked her if she went to the post office after a friend called and also asked for a card every day that week.

The drugs were allegedly sent to the prison between April 13, 2012, and Aug. 22, 2012.

According to the indictments, Stayrook became part of the conspiracy on Aug. 13 when he called Norwood and told her Morton wanted her to know she had a new pen pal. In a subsequent call that same day, Stayrook allegedly asked her about "doing it today and confirming that it was more than one," according to the indictment.

That day, prison authorities said Norwood mailed two envelopes to the prison with the drugs concealed under the envelopes' adhesive flaps.
