NASHUA – Incidents of sexual assault that occurred three years ago during a former church camp counselor’s overnight visit with a teenage camper in Nashua shattered the young victim’s faith in God and left him struggling to trust people, the thin, soft-spoken youth said during Wednesday’s sentencing hearing for the man charged with the offenses.

David Johansen, 28, of Carver, Mass., occasionally glanced at the victim, who turns 19 this month, as he recalled how he once looked up to Johansen, but now no longer goes to church because Johansen "used Christ against me."

Johansen on Wednesday agreed to plead guilty to one count of aggravated felonious sexual assault and two counts of felonious sexual assault in exchange for a 2-6-year term in the New Hampshire State Prison, where he must participate meaningfully in any recommended programs for sexual offenders and register as a sex offender, according to the terms of the plea agreement.

The plea and sentencing hearing, held at Hillsborough County Superior Court in Nashua, was the first of two such hearings this month for the 28-year-old Johansen.

The second is scheduled for Monday in a Barnstable County (Mass.) court, where he is expected to plead guilty to similar offenses accusing him of sexually assaulting two boys on various occasions between 2007-2011. Both boys were 14 and lived in Barnstable at the time.

Johansen was arrested for those incidents in August 2014, less than two weeks after police in nearby Cotuit took him into custody on a fugitive from justice warrant issued by Nashua police.

The Massachusetts charges include two counts of rape, and one count each of rape of a child with force and attempted rape of a child, according to a 2014 Cape Cod Times story. That plea agreement calls for Johansen to serve 4-6 years in a Massachusetts prison, a sentence that will run concurrent with the New Hampshire sentence, Assistant County Attorney David Tencza said at the Nashua hearing.

Both agreements stipulate that Johansen will report to New Hampshire State Prison on Tuesday. He is ordered to have no contact with the victims, and have no unsupervised contact with anyone under age 16, excluding family members.

When he is released from the New Hampshire prison, Johansen will report to the Massachusetts facility to serve the remainder of that term, attorneys said Wednesday. He is eligible, conditionally, to serve the final year of his term on home confinement, and will be placed on probation for 10 years when he leaves prison.

Tencza said Wednesday that Johansen will serve his New Hampshire sentence first so he can enroll in sex-offender treatment programs. Massachusetts currently has no such programs.

According to the Cape Cod Times story, one of the Massachusetts victims told police Johansen had sexually assaulted him "at least 100 times" over a one-year period, while the other said he’d been assaulted by Johansen "for three or four years."

Johansen and the Nashua victim met when Johansen was a volunteer counselor at Windsor Hills Camp and Retreat Center, a Christian camp for families, children and teens. Affiliated with the Church of the Nazarene, the camp is in the tiny town of Windsor in the northwestern corner of Hillsborough County.

In August 2012, Johansen contacted the victim and asked if he could stay overnight at his Nashua home to break up a long drive to his Carver, Mass. home, according to news reports at the time.

Johansen slept on the floor in the victim’s room, and at some point during the night the victim "woke up … his pants were down," and Johansen was performing a sex act upon him, Tencza said.

Johansen reportedly tried to contact the victim multiple times following assaults, but he didn’t reply, according to news accounts. The victim and a parent went to Nashua police in March 2014, at which time police reported the boy told detectives that the assault "had taken a piece of him away," and that "he was trying to get that back."

Nashua detectives subsequently went to Johansen’s Carver, Mass., home and spoke with him, at which time "he made admissions" to police, Tencza said. Reports state Johansen told police he thought the sexual acts were consensual, but that he also knew it was wrong because the victim was only 15 years old.

On Wednesday, the victim said that although "we’re here today because of something that happened several years ago," he continues to struggle.

"I don’t go to church. I don’t believe in God anymore," he said softly but firmly. "I have trouble trusting people."

Nevertheless, as he gets on with his life, "I hope you straighten yours out," he told Johansen.

In accepting the plea agreement, Judge Amy Ignatius briefly addressed Johansen.

"If there’s any good in this, it’s that you’re taking responsibility," she said of the offenses. "I commend you for that."
