"I would have expected between eight and 10 years, but I've heard rumours that it's as low as seven," he said.

Manzo added that if the Muzzo family – one of the richest in Canada – puts up a large donation toward a foundation and gives some money to the Neville-Lake family, the sentence could be lowered significantly.

Muzzo could serve as little as two years in a minimum security prison, considering he’s garnering 1-1/2 days worth of credit for each 24 hours he's in prison pre-trial. Furthermore, a prisoner typically serves one third of his sentence in Canada.

Manzo added that there is some precedence in Canadian sentencing where an injection of cash can draw a lighter sentence.

He referenced the North York California Sandwich shooting, in which the accused agreed to pay the unintended shooting victim, Louise Russo, $2 million in cash as part of the plea agreement.

Manzo said that while many will not be happy with the predicted sentence, he added that when the incident occurred, many suggested Muzzo wouldn't spend any time behind bars, considering he's the heir to a billion-dollar construction empire.

"Great lawyers can't make miracles," he said. "You can't buy yourself out of something like this."

Muzzo faces 18 charges, including impaired driving causing death.

Greenspan said he was not able to discuss Muzzo's case with the media.

At least two advocates, hoping Muzzo will receive a much tougher sentence than seven years, said this sort of wheeling and dealing has no place in our legal system.

Kathy Mitchell, the Stouffville-based president of the York Region chapter of MADD Canada, doesn't believe this sort of deal sets the right precedent going forward and will be bad for sentencing in the future.

"This is an opportunity for our judicial system to set a precedent," she said. "There have been catastrophic accidents in other parts of the country that have actually caused sentences to increase. When it's a big case such as this, it opens a door for stiffer penalties. This case shouldn't be decided by precedent, it should be about the details in this case, which has destroyed an entire family. All the money in the world will not change what has happened to this family."

The creator of the Facebook page, Prison 4 Marco Muzzo, responded to a request for comment, explaining the group is calling for life in prison for Muzzo.

"Not $1 billion can take away the pain for the Neville-Lake family," the comment stated. "Nothing will, unless we get justice, which is life in prison."
