Mounties on Sunday joined an ever-expanding search for an 11-year-old Calgary boy missing for three days.

Concerns over the welfare of Parker, a non-verbal, autistic boy last seen in Cambrian Heights on Thursday, are mounting and efforts to find him have drawn the support of RCMP, said Calgary police.

“We are grateful for that additional assistance (from RCMP) . . . as time goes by we are getting additional resources,” Acting Staff Sgt. Scott Guterson said Sunday afternoon.

“This investigation will continue until Parker is found.”

About 80 tips on his whereabouts have been received and followed up by authorities, who are also using Parker’s personal preferences gleaned from his parents in locating him, said police.

“Recently we’ve had police cars play themes from his favourite Disney music in hopes that will draw him out,” said Guterson.

A sign along 36th Avenue N.E. encourages Calgarians to search their property for missing 11-year-old Parker Wells on Sunday, July 19, 2026.

More than 300 CPS members — investigators, patrol officers, and members of specialized units including air support, mounted patrols, mountain bike and canine units — have been searching around the clock, investigating “every possible lead,” say police.

They’ve been bolstered by another 120 trained volunteers coordinated through Search and Rescue Alberta.

Parker is described as 4 ft. 11 in., weighing approximately 90 lbs., with brown hair and brown eyes. He was last seen shirtless, wearing grey shorts and black noise-cancelling headphones, at his day home on Connaught Drive N.W. sometime between 11:08 a.m. and 11:41 a.m. on Thursday.

Articles of clothing believed to belong to Parker were found around noon in the 0 to 100 block of Northmount Drive N.W.

Calgary police released a new image of missing child Parker, 11, captured on CCTV footage on Thursday at 12:52 p.m., taken in the 5000-6000 block of Travis Crescent N.E.

Searchers and those helping them continued to pass through the Thorncliffe-Greenview Community Association, where snacks, drinks and updates on the situation were circulated.

A few blocks away, at Thorncliffe School was another hive of activity — this one a command post for police and professional searchers.

Guterson said impromptu searchers should steer clear of areas being scoured by professionals but urged the public to carefully check their backyards repeatedly since Parker is mobile.

“Check every nook and cranny of your property . . . be constantly aware the little guy is still out there,” he said.

Parker, he said, has a tendency to lock doors behind him, so even doors that are secured should be opened and the space checked.

While police voiced gratitude for the public’s interest in finding Parker, they also expressed concern over the welfare of helpers, whose own needs could detract from the search.

“Given the heat and the inherent risks associated with searching, there is a significant possibility that large groups of well-intentioned volunteers without search-and-rescue training may require assistance themselves,” said police.

In a statement released Saturday, the boy’s family expressed thanks for those working to find him and anguish over his continued absence.

“Since he went missing, our family has been living every parent’s worst nightmare. Every hour that passes without knowing where he is or whether he is safe has been incredibly difficult for us,” the statement said. “Parker is deeply loved, and he is missed immensely. We just want our son home.”

‘No equivalent emergency notification for vulnerable individuals,’ says Calgary mom

On Saturday afternoon, an Amber Alert on Parker was broadcast — an anomaly given the boy isn’t believed to have been abducted.

But police said the level of concern for Parker’s safety necessitated the move.

The Calgary mother of a special needs child said that system should more regularly take into account situations like Parker’s.

“There is currently no equivalent emergency notification for vulnerable individuals who may not have been abducted but who are still in immediate danger due to conditions such as autism, intellectual disabilities, dementia, or other medical or developmental challenges,” said Jennifer Ball, the mother of a non-verbal autistic child.

“If my son were ever to wander, every minute would matter. He cannot tell someone his name, ask for help, or explain where he belongs. Waiting many hours — or even days — for widespread public awareness could have devastating consequences.”

She said she has started a petition to create an alert category based on those emergency criteria that don’t involve abductions.

“This isn’t about replacing or weakening the Amber Alert system. It’s about filling a gap that currently exists and helping bring vulnerable people home safely,” said Ball.

Anyone with information about Parker’s whereabouts, or who may have CCTV or dashcam footage of Parker, is asked to contact police by calling 403-266-1234 or by submitting footage online. Tips can also be submitted anonymously to Crime Stoppers by phone at 1-800-222-8477 or online through the Crime Stoppers website or P3 Tips app.
