After an investigation, Saskatchewan police say they have found no evidence linking bullying to the death of a 15-year-old boy in North Battleford.

Todd Loik's mother Kim went public in September 2013 with concerns over cyberbullying. She said older boys at school constantly tormented her son online.

She discovered the body of her son in their home on Sept. 9. The student at North Battleford Comprehensive High School took his own life two weeks before his 16th birthday. 

Asked by CBC to comment, Kim Loik replied on Facebook. 

"I'm not sure I am disappointed because [there are] no laws for this," she wrote. "They need to work harder on it for the kids that have lost their [lives] at the hands of others. This is happening and it will continue to happen as long as [there are] no laws."

Police said they determined during their initial investigation that Loik's death was not suspicious or criminal in nature and that he did not die from natural causes. 

After Kim Loik provided the RCMP with additional information, they reviewed more than 16,000 texts on the boy's phone, along with hundreds of Facebook postings and dozens of videos.

On Tuesday, the RCMP said in a news release they did not find any evidence of criminal harassment.

"After complete analysis of everything, we did not discover anything that supported that theory," Sgt. Neil Tremblay said. 

Police also said that prior to the incident of Sept. 9, 2013, police had received no complaints from Todd Loik, his family or any other person relating to harassment or other criminal behaviour. ​

Kim Loik said she has sent in a request for access to information to her son's case will wait for that.
