It's been nearly two years since Paul Bennett was gunned down in the driveway of his Cloverdale home.

"I think the issue here is the code of conduct is too restrictive. It's a straight jacket for trustees," the education consultant said.

Global News has obtained eight letters addressed to Suzanne Ruttan, chair of the LDSB, asking for the provincial investigation.

The expert says he hopes parents will rise up and demand a provincial investigation of Kingston's public school board.

In an exclusive interview with Global News, Supt. Dave Chauhan says the unsolved case of Paul Bennett's murder is one of his top priorities.

"I'm scared every day because I don't know who did this. I have no answers," said Darlene Bennett, the widow of Paul Bennett, who was shot and killed on June 23, 2018.

Paul Bennett's wife says the lack of a plan on how to investigate homicides under the Surrey Police Department is one reason why she's confused about the transition.

'No closure, no answer, I think, is what has been so difficult for everybody on why this happened.'

'We are grieving and traumatized by his loss and praying to understand why this has happened to our family,' said Paul Bennett's wife.

Police are asking for any information, but are specifically interested in video surveillance.
