More than a year has passed since 27-year-old Chad Smith was shot and killed while delivering a pizza in Dartmouth, Nova Scotia and now the province is offering a $150,000 reward for information that leads to the conviction of his killer.

Smith's family is also begging for answers and says the only thing they want this Christmas is justice.

"I promise my son that as his mom, I will never stop fighting for justice for him," says Louise Smith. "I'm just hoping people will have a heart. It's Christmas. Please come forward with any information."

Smith was killed on October 23, 2010 as he was delivering a pizza to an apartment building on Joseph Young Street in the north end of Dartmouth. Police say he was fatally shot just before 9:30 p.m.

On the night he was killed, police say the call to the pizza shop came from a phone booth located outside on Highfield Park Drive between Joseph Young and Burnside Drive.

They believe the person who made the call may know something about Smith's death, and they are hoping the reward money will jog someone's memory.

"It's another avenue…to reach out to the public," says Const. Brian Palmeter, a spokesman with Halifax Regional Police. "If people don't want to come forward because it's the right thing to do, then obviously now there's a significant monetary reward out there to help coax them into coming forward with information."

There are now 63 cases in the government's Major Unsolved Crimes program. The $150,000 is only handed over if there is an arrest and a conviction.

Police say that while they have received some helpful information, none of the cases have been solved, and the money has never been handed out.

Besides being an older brother, Smith was also a father to two young girls and his family says he liked to talk and loved to laugh.

"It's hard because you know that person's walking around," says Smith's cousin, Stacey Devoe. "They get to spend time with their family, but Chad, his family…we don't get to see him at Christmas."

Today the family hung posters around Dartmouth, hoping they might encourage someone to come forward with information.

"This is our gift to Chad, that we went out today, putting up these posters," says his mother. "Although we don't have him, it's our Christmas gift to him, and hopefully we'll find justice for him."
