The fiancée of missing Saskatoon man Myles MacIntosh is calling on the government to require bars to be more responsible for their patrons.

In an exclusive interview with CBC's Steve Pasqualotto, Michelle Kohle — who still has the feather bouquet she was supposed to carry at her wedding — spoke about the circumstances leading up to her husband-to-be's disappearance.

The wedding ceremony never happened because MacIntosh went missing following an incident at his stag party and is presumed to have drowned.

"It's hard to believe this is real life," Kohle said Monday. "This shouldn't be happening."

MacIntosh's party was held at the Saskatoon bar Outlaws. He was asked to leave the bar and hopped aboard a pub crawl bus that was head for another lounge on 8th Street. During the trip, at the intersection of Lorne and 8th, an altercation arose.

By the time police arrived, MacIntosh was off the bus. Officers were then told that a man had fallen in the South Saskatchewan River. Recent DNA analysis has confirmed that blood found on the riverbank in the area came from MacIntosh.

Kohle believes the tragedy could have been avoided if MacIntosh was given more time when told to leave the first bar.

"If he had just been given a minute to go and get his friends or if they had paged his friends [or] if they realized he didn't have a wallet to get into a cab, he would have been able to get home safety with his friends," Kohle said.

Since the incident police have charged the bouncer on the bus, Scott Denny, accusing him of aggravated assault.

Kohle said MacIntosh should not have been able to get on that bus because he lacked a pass.

She is calling on the province to examine the relationship between bars and their customers.

"I want the laws somehow changed," Kohle said. "I don't know how, [but] I want the bars to be more responsible to their patrons and [as for] pub crawl buses, there needs to be better security."

Kohle said it has been difficult for her to contend a future without MacIntosh.

"It's really hard," she said. "I want to be able to find him and bring him home to his parents."

Authorites said a search of the river, for MacIntosh's body, would resume in the spring.
