A young Whitehorse man with a long history of violence today pleaded guilty to creeping into a Porter Creek home and molesting a young girl while she slept.

Anthony Skookum was sentenced to two years less a day by Yukon Supreme Court Justice Leigh Gower.

The judge gave the 21-year-old man time-and-a-half credit for the 11 months he has already spent behind bars.

In court today, Skookum admitted to entering a stranger's home early on the morning of May 28, 2010. He crawled into bed with the two young children living there, removing the girl's underwear as well as his own, and touching her genitals.

He was very drunk at the time, according to Skookum's legal aid lawyer, Emily Hill, and does not clearly remember the incident.

But the girl and her family do.

According to an agreed statement of facts read into the record today, the girl's seven-year-old brother awoke to find Skookum in the bed, lying behind his sister (who was described only as "well under the age of 18”).

The boy jumped out of bed and ran to his 18-year-old brother's room for help. When the two boys returned, they saw Skookum pull up his pants and leave the house.

Although he did not know Skookum personally, the older brother recognized Skookum well enough to identify him to police.

The girl told investigators that Skookum was touching her for a few minutes and that he didn't physically hurt her.

A further medical check revealed no bruising nor other signs of force.

A wallet containing Skookum's identification was found at the foot of the bed, and a pair of men's underwear and a pair of running shoes believed to belong to Skookum were also found in the house.

He was arrested two days later, and was co-operative with police, according to Crown prosecutor David McWhinnie.

He was charged with sexual assault, sexual interference of a child, breaking and entering, and being in a home unlawfully.

Although the facts read into the record today support all of those charges, Skookum only entered a guilty plea to sexual assault in return for a joint submission on sentencing.

"For someone so young ... he has a disturbing record,” McWhinnie said before launching into a litany of convictions for violent crimes on Skookum's record.

In 2006, Skookum was convicted of sexual assault, a crime which got him removed from an otherwise stable and caring foster home and put into a group home.

The next year, he was convicted of stabbing a young man in the chest, then smashing another teen in the face with a shovel.

In 2008, he was again charged with a stabbing, but was found not guilty by a supreme court jury.

In 2009, he was convicted of possession of stolen property, although the prosecutor noted Skookum had not actually taken the purse, but ended up with it somehow.

According to various psychological assessments and reports, Skookum has "a very significant potential for violence,” McWhinnie said, "both physical violence and sexual violence.”

Although Skookum has serious drug and alcohol abuse problems, "his capacity for violence seems to exist independently of alcohol,” McWhinnie noted.

A "terrible upbringing” is at least partly to blame, the prosecutor said.

Skookum's mother died after years of heavy drinking, McWhinnie said, and his father killed himself after being charged with assaulting his then-six-year-old son.

Skookum's lawyer also highlighted his "chaotic” upbringing.

She pointed out that a strict three-year probation period is necessary to provide the kind of focused support a person might otherwise get from stable family members.

"He has no one here today to support him at sentencing,” Hill said, motioning to a court gallery occupied only by two journalists and a victim services worker.

"He has no one waiting for him when the doors open at WCC.”

Gower accepted the joint submission of two years less a day, as well as the credit for 17 months already served.

For three years following his release, Skookum must remain in the Yukon, the judge ordered.

He must not drink or use drugs, he cannot have any contact with the victim or her family, nor can he go near her house.

He has to attend various treatment programs and he cannot have contact with anyone under 18 years old.

The judge also imposed a mandatory 10-year firearms prohibition.
