Don Dunphy, 59,was shot and killed by Royal Newfoundland Constabulary officer Joe Smyth on April 5, 2015.

The shooting in the tiny community of Mitchells Brook set off a firestorm of questions and controversyfrom friends and supporters of Dunphy as well as the public.

The RCMP concluded there will be no charges against now-acting Sgt. Symth. And an investigation into the handling of the Dunphy case,by the Alberta Serious Incident Response Team or ASIRT found the RCMP's investigation was "thorough, complete and unbiased."TheSaskatoon Police Service found, according to the RNC, no wrongdoing on the part of Smyth and the force.

The last [shot] ...I wonder about all of them ... were they needed?- Retired justice David Riche

None of those reports have been released publicly, citing fear of hampering the upcoming public inquiry.

That didn't stop former justice David Riche, who acted as an independent observer,from providing new details andinsight into what happened thatday.

Here's what we learned from conversations with him.

1. Four shots fired

Riche said Dunphy was shot four times in his home, at close range. "I'm talking about three of four feet," Riche told the CBC's Carolyn Stokes Tuesday.

"His last bit of shooting was near the victim's head," Riche said.

The number of shots fired, Riche said, was a concern as it showed there was "an intention to kill."

"Therewasn'tanintentto stop, intention to wound. There was no indication of shots being fired back at him. The last shot was so close that you say to yourself, why?"

"The last [shot] ...I wonder about all of them ... were they needed?"

2. Angry men

From Riche's perspective, the altercation was between "two angry men."

Through Riche's own sources, he said, he was told Dunphy was mad, having been fighting with government for decades as an injured worker.

As for Smyth, Riche said "there was anincidentone time when [Smyth]got into difficulties himself. Hecouldbe aggressive ...that was my impression, that this was a man who could beaggressive.

3. 15 minutes

According to Riche, 15 minutes passedfrom the time Smyth walked into Dunphy's home to the moment four shots rang out in the St. Mary's Bay community. It took 20 minutes, Riche said, for the RCMP to respond.

Riche said Smythwas speaking to Dunphy when "something happened which caused Smyth concern. He drew his weapon and fired shots."

4. Gun not cocked

While Riche could not say if Dunphy's gun was loaded, the former justice said the gun was not cocked.

"Idon'tthink it could have been fired as itwas, unless you did something. You need to close the action," he said.

Riche was not allowed to interview witnesses or Smyth. He did, however, speak with Dunphy's daughter, Meghan Dunphy.

As Riche pointed out, "dead men tell no tales." And the only other person there that day hasn't answered outstanding questions, which may be part ofa promised public inquiry.
