A former Sununu Youth Services Center counselor is accused of giving sex, alcohol and guns to a teenager sentenced to the youth detention center on separate occasions in Concord, Laconia and Manchester.

Police allege Kirstie Bean, 25, of Concord also gave the 15-year-old and an 18-year-old pistols this past July when the three were in Laconia. She is also accused of purchasing alcohol for the two teens and allowing the 15-year-old to drive a vehicle in Manchester and in Alton.

Court records do not say whether the 18-year-old was ever a resident of the youth detention center.

New Hampshire State Police filed an arrest warrant with Manchester Judge William Lyons on Nov. 30. Police arrested Bean soon after on 12 charges, including four felonies. The cases against Bean will proceed in three separate district courts in the state.

In Manchester, she faces one count each of felonious sexual assault and witness tampering, as well as three misdemeanor counts of endangering the welfare of a child. She posted $2,500 bail following her arrest Dec. 1.

Additional counts of aggravated felonious sexual assault, hindering apprehension or prosecution, endangering the welfare of a child and sale of firearms to minors were filed in courts in Laconia and Concord.

Bean is accused of having sexual intercourse and other sexual contact with the 15-year-old between August 2015 and August 2016. She told the boy not to talk to anyone about their “relationship” after she learned of the police investigation, according to court records.

The state Department of Health and Human Services operates the Sununu youth center in Manchester. In court documents, Bean lists the center as her former employer. A spokesperson confirmed she no longer works there.

Bean worked as a summer camp counselor at the Pines Community Center in Northfield between 2008 and 2014 and as a substitute teacher at the Keene Day Care Center between 2012 and 2014, according to her LinkedIn profile. As of Friday morning, Bean’s profile had been removed.

The Pines Community Center had no comment Friday about the allegations against Bean in area towns. The center was in the headlines earlier this year after its former maintenance worker, Robert Magoon, was accused of sexually assaulting seven girls and one woman while employed there. The case against Magoon is pending in Merrimack County Superior Court in Concord.

Last week, Bean’s attorney, Cathy Green, entered pleas of not guilty on Bean’s behalf in Manchester’s district court. Bean also waived her arraignment which was scheduled for Jan. 9.

State police Detective Kelly Healey, who investigated Bean, could not be reached for comment Friday. The Hillsborough County Attorney’s Office said it had not yet received any state police records and didn’t have any knowledge of the investigation in Manchester.

Bean is prohibited from having contact with anyone under the age of 16, as stipulated by her bail conditions. The exception is at family events where she must be supervised by an adult when in the presence of someone 16 years of age or younger. She can also not be within 1,000 feet of the youth detention center.
