Brothers with FAS who raped teen need structure, supervised environment: lawyers

CALGARY — Lawyers for two brothers with fetal alcohol spectrum disorder who repeatedly raped a teenage girl say their clients should spend years in prison.

Sentencing arguments continued Thursday for Corey and Cody Manyshots, who pleaded guilty in October 2015 to kidnapping, uttering threats, sexual assault and robbery.

Corey's lawyer, Mitch Stevenson, is asking for about 6 1/2 years behind bars, including time already in custody.

Alain Hepner, who is representing Cody, has proposed a total sentence of about nine years.

Court has heard the brothers suffer from fetal alcohol spectrum disorder, have poor cognitive function and struggle with mental illness.

"These two men fell through the cracks of life," he told court. "They didn't stand a chance from the minute they were born."

The pair approached a 17-year-old girl at a northeast Calgary bus stop in November 2014, forced her into an alley and sexually assaulted her.

The brothers, both in their 20s, then abducted the Grade 12 student and took her to their home, where they sexually assaulted her another 15 times until she was able to escape about eight hours later when they fell asleep.

Reports presented as evidence say the two should be in a structured, supervised environment where their unique needs can be addressed.

Hepner said there is no treatment for FASD, but he hopes there is a way the brothers can get the support they need to lead a meaningful life once their sentence ends.

The Crown had earlier proposed a 12-year sentence. Crown prosecutor Jonathan Hak there is a relatively high risk the two will reoffend and they show little empathy for the victim.

Having the brothers stay voluntarily at a residential facility following their sentence should not be seen as a solution, he added.

"I think in the real world, that's not going to happen," he said.

Hepner presented a statement on behalf of his client, who he said cannot read, in which he said he is sorry for causing pain to the victim and that he wants to get counselling.

The defendants' mother, Angelina Manyshots, also addressed the court.

"I really love my sons," she said. "I'll do everything I can to help them."

Provincial Court Judge Terry Semenuk said he expects to deliver his decision on Jan. 26.
