One of two teens charged in the Rehtaeh Parsons child pornography case is now accused of threatening to kill the girl’s father, Glen Canning.

Police said Saturday that a 19-year-old Eastern Passage, N.S., man is facing charges of uttering death threats and criminal harassment after allegedly making threats online.

Canning wrote on his blog Saturday that's he's relieved there will be charges, but said: "it’s sad someone so young has made such a mess out of their life and chosen to lash out in such a way."

The general investigation unit of the RCMP and Halifax Regional Police launched an investigation after getting a complaint on Aug. 2, 2013.

The charges stem from comments written underneath a YouTube video posted by Canning. Police said other threats were made on WordPress, an online publishing platform.

Canning said credit goes to police for tracking down a suspect, but he added that investigators were slowed because Internet giant Google took months to respond to requests for information.

"Hopefully social media companies are learning to be more responsive to police requests for information and in the future response times will be much shorter," Canning wrote.

"People who turn to the Internet to harass and threaten others and believe they are doing so in darkness need to know police are getting better at turning on the lights. You are not as hidden as you think."

Police have not released the identity of the person charged, but sources confirm to CBC News the suspect is one of the teens accused of child pornography-related offences.

Police said they executed search warrants to get IP addresses and other information. Officers seized computer and electronic storage devices from a home in Eastern Passage.

The teen is scheduled to appear in Dartmouth provincial court on May 20.

Last August, Canning said publicly that he’d received an online death threat on his YouTube channel.

"‘I know where you live, I know your face, I know your car, I know your house, I know where you work. And you better shut up, bud, or you're going to be joining your daughter.’ Just stuff like that. It's pretty sad, actually," Canning said at the time.

The Parsons family says the girl was sexually assaulted by four boys at a party when she was 15 years old, and then a digital photo of the incident was circulated at school and on social media.

The 17-year-old died last April. She was taken off life support a few days after a suicide attempt.

Police initially did not lay charges, but reopened their investigation and have charged two teens with child pornography-related offences. That case is due back in court later this month.

Parsons' death made international headlines and prompted new laws cracking down on cyberbullying.

Earlier this month more than 150 people marched in Cole Harbour, N.S., to mark the first anniversary of her death.
