The parents of Tyler Clementi, the gay Rutgers University student who jumped off of the George Washington Bridge to his death in 2010, talk about the tragedy in an interview with NBC News airing tonight (28 June).

Tyler was just 18 and committed suicide after his roommate, Dharun Ravi, spied on his dorm room encounter with another man then discussed what he saw on the webcam with friends on Twitter.

James Clementi admits that his son was struggling with depression but says Ravi's spying and the humiliation that followed 'was the straw that broke the camel's back.'

Added Jane Clementi: 'I think it was – it was the humiliation that his roommates and his dorm mates were watching him in a very intimate act and that they were laughing behind his back. The last thing that Tyler looked at before he left the dorm room for the bridge was the Twitter page, where Ravi was announcing Tyler's activities.'

Ravi was found guilty in March of bias intimidation, invasion of privacy, and tampering with evidence. Bias intimidation is a hate crime based on the fact that Clementi was gay.

He could have been sentence to up to 10 years in prison then deported to his native India. Instead, he received a 30 day jail sentence of which he served 20 days before being released early. He will also not face deportation.

Ravi aside, Jane Clementi talks about her Christian faith in the interview and how it affected her reaction when her son came out to her only a few weeks before his death. She says the news came as a 'shock' that she was in the process of 'trying to just accept it.'

Her son misread her reaction as rejection and texted a friend about it, the mother later learned.

'It just was like a dagger,' she says. 'And that took me a long time to process. Because I did not think I had rejected him.'

Clementi’s parents say they hope The Tyler Clementi Foundation will discourage cyber bullying and dispel the notion that they themselves once held that homosexuality is a sin.

'Sin needs to be taken out of homosexuality,' says Joe Clementi.  'Our children need to understand – and adults need to understand – that they're not broken.'
