Four years ago today an Estevan family was over a month into what Gerry Alexander said was like being in a horror movie, 24/7, as they searched for Gerry's missing 33-year-old son Geoffrey Alexander with very little information.

Gerry said they weren't sleeping or eating properly, and that they were running off adrenaline.

And then on December 21, 2015, Geoffrey's remains were found in a valley in the west part of Estevan. He'd been missing since November 12.

Two weeks ago the Estevan Police Service classified Geoffrey's death as suspicious, but the family is still desperate for answers.

"We have since been just distraught, and can't figure out what happened to him or how it happened to him, and nobody's come forward. And like every year, it's a trigger this time of year, trying to cope with what happened to him."

On November 11, 2015, Gerry saw Geoffrey for the last time at Gerry's daughter's belated birthday party around 8 p.m.

Geoffrey was living with his mother Janice at the time, and on November 12 left her apartment around 2 or 3 p.m., saying he was going for coffee with a friend. And then he disappeared.

"There was no trace," said Gerry. "He never texted, he never phoned; we knew something was up."

Gerry said they went to the police station and let them know Geoffrey was missing, and then the police put out a missing person report and had it on Facebook. But Gerry said nobody was coming forward with any kind of information.

"We were wondering what we were supposed to do while he was missing," Gerry said. "We put out posters, we put out an interview with a Regina tv station, and we just kept hoping that we would find him, but never had any real clues as to where he was."

Over the last four years Gerry said they've kept in touch with the police, but there hadn't been new information until there was a status change two weeks ago.

"The explanation they gave was they'd been putting little pieces of the puzzle together; they can say that it's a suspicious death."

Gerry hopes that sharing what the experience has been like will result in someone coming forward with information.

"I'm trying to just relay sort of what the family goes through when they have a loved one that has a death that's suspicious. Your son is found in a valley, and only the remains - only parts of him were found. It's hard enough to know that your loved one died, but to die the way Geoff died, we don't know. We don't know whether he suffered before he died. We don't know the circumstances of his being missing. We looked for him for over 33 days and we did find him before Christmas of 2015, but we still don't have any answers.

"This is what a family goes through when there are no answers, and we're just hoping that someone will come forward and give us the closure that we deserve as a family, as a parent, as a sister, as a brother, as a daughter that Geoff has. We deserve to have the answers of what happened to our son.

"I'm just hoping this interview will bring out the people that know answers - that possibly they'll have a conscience and move forward and go and tell the truth so we can have some closure for our son and ourselves."

So far the Estevan Police Service hasn't commented publicly on why the status of Alexander's death was changed to suspicious.
