Wednesday marks 20 years since David MacDermott’s family last saw or heard from him.

The 30-year-old Kitchener resident mysteriously went missing in 2002.

“Now he'd be 50, I can't even imagine,” his mother Linda Shaw told CTV News. “You know, what he would look like? Would he have a family? Children?”

His family is making yet another plea to the public to help them find out what happened.

MYSTERIOUS DISSAPEARANCE

Since the day David went missing, his family says they’ve been left with very few clues.

“He was planning on going out for a friend’s birthday,” one of David’s sisters, Colleen Stevens, explains.

On the night of his disappearance, David went to what was then Club Renaissance in downtown Kitchener. His family was told after the bar, he went to a friend’s house.

“Neighbours had reported they heard a fight, but they don’t know who was involved. Other then that, we have very little,” his mother says.

According to Waterloo regional police, David was last seen that night at his residence on Mill Street.

David was supposed to meet friends and Colleen the next day, but never showed for either commitment.

“I just had a feeling that something wasn't right,” Colleen says.

Just days after he disappeared, police confirm a dog matching the description of David’s was found wandering the streets near his home.

A few months later, officials say David’s car was found near his home too.

DAVID ‘WAS ALWAYS SMILING’

David’s mother and younger sisters spread photos of him out on the kitchen table, while sharing memories.

Linda says staff nicknamed him “prince” when he was born, because he was the only boy born in the hospital that day.

“He was a fun happy go-lucky guy,” Colleen says. “He knew a lot of people, had a lot of friends and was always smiling.”

David’s youngest sister, Amanda Shaw describes him as, “the standard protective big brother.”

The 30-year-old went missing just before Amanda’s 11th birthday.

“A lot of the memories I have with him, unfortunately are lost,” she explains.

THE LONG SEARCH FOR ANSWERS

His family and investigators are convinced the answers they're looking for are still with a person or people in our community.

“Twenty years is a long time to hold such a secret,” Colleen says.

She adds she gets angry knowing “there is someone that knows what happened to him.”

That’s why the family continues to share his story, hoping to find answers.

“I am begging them, please help us to do this,” his mother Linda adds, appealing to those with information.

“If somebody has it in their heart to be able to help us move on from this and be able to put David to rest.”

“We just want answers,” Amanda says. “And more than anything, we just want to lay my brother to rest and have that closure.”
