School boards in Edmonton sent letters home with students this week warning parents about the release of a high-risk sex offender in Edmonton late last month.

On March 26, RCMP warned the public about the release of Bruce Donald Windsor, 48, who was released from custody after serving a two-year sentence for possession of child pornography, accessing child pornography and sexual interference.

Schools also sent parents a copy of the RCMP news release containing Windsor's picture.

Edmonton Public Schools sent the notice home with every student in the system, a move communications supervisor Jane Sterling said was "very unusual"

"We felt that it was important to get that information out to parents," she said.

The notice would give parents a chance to make sure their children were reminded of important safety measures, like not talking to strangers and telling parents or teachers if a stranger approaches them, the letter said.

Edmonton Catholic Schools sent the notice to all of its principals with a recommendation it be forwarded to students, spokesperson Lori Nagy said.

"This time we felt because he's at a high risk to reoffend and he's living in the Edmonton area that we thought it was important that we give parents that information," she said Thursday.

The RCMP put out the warning because, according to the news release, it was felt Windsor posed a "considerable risk" to the community.

"With high risk sex offenders when they're released from jail we do a risk assessment and decide whether we need to advise the public if he's a high risk to re-offend," said Const. Barb Roy from the Spruce Grove/Stony Plain RCMP.

"And in this case, he is not treated and there's a high risk to re-offend. He poses a risk especially to young females."

According to the RCMP warning, Windsor must follow a 20-year order that bans him from being in a public park, public swimming area, daycare centre, school ground, playground or community centre where there are children under 14. 

He is banned for life from having a paid or volunteer job that would put him in a position of trust with children under 14. He also has a lifetime ban on using a computer to communicate with anyone under 14.
