It’s been about 25 years since Clayton Miller was found dead, face down in a brook two days after police raided a party in the woods in New Waterford, N.S.

Today his parents, Gervase and Maureen Miller, met with director of Nova Scotia’s Serious Incident Response Team and the province’s chief medical examiner in Sydney, and though they said it was a step in the right direction, they’re still not satisfied.

“(SIRT director) Ronald MacDonald is more or less the one mainly in charge, and just from what was done from this point and what’s left to do, he came across in such a way that I’m not going to get my hopes up,” Gervase Miller said.

“They seemed very upfront with us, and it’s what they can prove, that’s what they’re looking at,” Maureen Miller said.

At the meeting, which lasted nearly four hours, the Millers presented investigators with evidence they’ve gathered for nearly 25 years, outlining their theory that police were involved in their son’s death.

“We came here with an open mind to listen to what the Millers had to say. I kept my mouth shut and ears wide open,” said Dr. Matt Bowes, Nova Scotia’s chief medical examiner.

“It’s clear the Millers do possess information we need to consider,” he said.

SIRT received a tip recently that, if accurate, would suggest a current member of the Cape Breton Regional Police has information on the Clayton Miller case that they are withholding.

MacDonald said the new probe will be difficult given how much time has passed.

“That does give significant challenges, but in the end the test is the same: What can we find, if anything, that could say whether or not there should be charges against a police officer, like in any one of our investigations,” MacDonald said.

During the meeting, protestors waited peacefully outside.

Stephen McNenly said he attended the protest “to show my respect for the family and my disrespect for what has taken place against them.”

Ray Wagner, the lawyer representing the Miller family, plans on meeting with MacDonald and Bowes again next week in Halifax to hand over audio recordings and other documents relevant to the case.
