It's been four years since 6-year-old Lauren Belius was murdered in her Sherrill home by her mother's then-boyfriend, David Trebilcock. On Thursday, Lauren's mother, Allison, made an appearance on the Dr. Phil Show. She shared their story and asked the millions of viewers for their support. Cara Thomas reports.

The gruesome and horrific murder of Allison Belius' 6-year-old daughter, Lauren, is something that plays through her head every single day. 

"You know, I've always said, I don't think any of us were meant to leave that house that day. So it's always a fear that he will come back looking for us, finish the job or maybe he'll go on to somebody else, you don't know," said Belius. 

Lauren was stabbed to death by her mother's then-boyfriend, David Trebilcock. He stabbed her 24 times and only stopped after being stabbed and knocked unconcious by Belius. She says the attack lasted nearly half an hour. 

Trebilcock was found not responsible by reason of mental disease or defect. 

"As it stands right now, he is evaluated every two years by his psychiatrists and at any time if they feel he's been treated successfully and is well enough to be discharged, he could be released from the mental hospital," said Belius. 

After hearing of her family's story, producers from the Dr. Phil Show reached out and Belius agreed to be on the show, but her main goal was to send an important message, that people like Trebilcock should serve a full sentence. 

"We just don't feel insanity should be a get-out-of-jail-free card," Belius said while on the show. 

Since Trebilcock's sentencing in 2012, Belius has been working alongside state Sen. Joseph Griffo to create legislation which would keep a mentally ill person in a facility of some sort for the full length of an appropriate sentence. That proposed legislation has been called the Lauren Sylvia Law. 

"Something needs to be done. This isn't right. It's not fair. It's not a good outcome at all and it wasn't justice for Lauren," said Belius. 

This legislation was created to help any family impacted by a situation like this in the future. If passed, this law would not change Trebilcock's sentence. He could be released at any time. 

A petition has been created to help with the passage of Lauren Sylvia's Law. They need at least 500,000 signatures. They are also asking people to speak to their local representatives about supporting this legislation.
