The RCMP say more than 400 tips have been received in connection with the death of Amanda Todd.

The 15-year old took her own life this week -- after years of bullying -- much of it online.

But even in death -- Amanda is still the target of heartless online abuse.

From online trollers posting hurtful messages and images on pages dedicated to Amanda's memory.

RCMP Sergeant Peter Thiessen says those people run the risk of being criminally charged.

"The family, the police, the community in general are really quite outraged by the conduct of many on social media."

More than 20 full-time investigators are assigned to the file.

Thiessen says tips have been coming in from all over the world -- although he couldn't speculate on reports from Amanda's mother -- that Amanda may have been the online target of an American pedophile.

Meanwhile, Premier Christy Clark says parents need to have a bigger focus on watching their children on social media.

"We have to educate parents about how important it is that they 'friend' their kids on Facebook. You need to be a part of their online life! You need to be dropping into their e-mail every now and then, particularly when they're younger and they'll let you... I recognize that's harder as they get older... but you need to be engaged in your child's online life."

Clark was speaking with Sean Leslie on CKNW's The World Today Weekend.
