The search continues in Saskatoon for Myles MacIntosh, the 28-year-old man who disappeared at his own stag party Saturday. 

CBC News spoke with the Mayor of Lunenburg, Nova Scotia, MacIntosh's hometown. She said Wednesday the news has rocked the eastern community. 

She said MacIntoshe's friends are reaching out to his family to offer any help they can. 

A makeshift memorial showed up on the banks of the South Saskatchewan river Wednesday, with several flower bouquets and a football. 

It's near the spot where two witnesses reported seeing a man walk onto the river ice on Saturday night, and disappear out of sight. 

MacIntosh's family is convinced that he was the person who was seen falling into the river. 

They told CBC MacIntosh was thrown out of Outlaws bar during his stag party at around midnight- close to the time people saw the man walk onto the ice. 

Saskatoon police are treating this as a missing person case. They said they're still getting tips from the public and interviewing anyone with information. 

At this point, they still consider this an active investigation and are trying to retrace MacIntosh's steps that night to see if they can find out for sure if he's the person who fell in the water. 

His family has posted pleas on Facebook asking anyone with information to contact police.
