Ex-scout leader David Wolfe pleads guilty to fourth sex charge

Former New Brunswick scout leader David Wolfe has pleaded guilty to a fourth sex-related charge dating back to the 1960s.

Wolfe, 68, who now lives in Halifax, made a brief appearance in Moncton provincial court on Wednesday, dressed in a suit and tie.

He pleaded guilty to indecent assault involving a boy in the Port Elgin area between 1962 and 1964.

Wolfe had previously pleaded guilty to three counts of indecent assault involving young males in the Moncton area between 1964 and 1967.

He will be sentenced on all four charges on March 21.

The Crown and defence plan to make a joint recommendation on sentencing, the courtroom heard.

A sentencing hearing was expected to be held on Wednesday, but the court has not yet received a victim impact from the latest victim and the defence wants Wolfe be sentenced for all four charges at the same time.

The latest victim came forward in January, after Wolfe pleaded guilty to the other charges.

​Codiac Regional RCMP charged Wolfe in 2012 after the first victim, Richard Dutkiewicz, went public with his story.

Dutkiewicz told CBC News he was repeatedly assaulted by Wolfe in the mid-1960s, when Wolfe was an assistant scout master. He said the abuse — oral sex — occurred at Wolfe's home, not far from West Riverview School, where the scout meetings were held.

Dutkiewicz said he suffered years of shame and guilt, which cost him his 27-year marriage and strained his relationship with his three children.

He only went to police in 2011, after he saw an investigative series by CBC News on sexual abuse within Scouts Canada.

The investigation by CBC-TV's the fifth estate revealed that scout leaders abused about 340 children from the 1940s until present.

It also found that Scouts Canada kept a "confidential list" of pedophiles barred from the organization and had also signed confidentiality agreements with child sex abuse victims.

About two months after the documentary aired, Scouts Canada issued a blanket apology to any former scouts who had been sexually abused by the group's volunteer leaders.

The youth organization also announced it had hired an outside company to review its past records and appointed an expert panel to examine whether its current child protection policies are working.

Police located Wolfe at the Dartmouth Seniors Service Centre in Nova Scotia, where there was a picture of him on the website as the centre's treasurer, according to Dutkiewicz.
