Leah Parsons, of Nova Scotia,  said she took her daughter, Rehtaeh, off life-support Sunday after she hanged herself last week. She said one boy took a photo of the alleged assault in 2011 and her daughter was subjected to bullying after it went viral.

Police concluded there were no grounds to charge the four boys after a year-long investigation, according to the CBC.

Royal Canadian Mounted Police Cpl. Scott MacRae said the investigation was completed in consultation with prosecutors and said there was insufficient evidence to proceed with charges, the network reported. Nova Scotia Justice Minister Ross Landry said he has no plans to review the case because he has no reason to doubt the integrity of the police investigation. Landry said he has yet to hear of any formal complaint from Parsons about the police investigation, though he added she was able to file one.

According to the CBC, hundreds of comments were posted on a Facebook page set up in tribute to Rehtaeh's life demanding someone be held accountable for her death.

"Clearly the justice system failed her, society failed her, the school system failed her, the mental health system failed her," one post said.
