Ms Raspa’s phone was found in a small lakeside park, some five kilometres away, about 6.30am the following day, however exactly what happened remains the cause of much speculation.
Rescue helicopters, fire department crews and divers have been searching the region, but poor weather and fresh snowfall have hindered search efforts.
Alison's devastated mother and brother have flown to the popular ski village, with a friend of the family telling NewsCorp that Ms Raspa was upset about 'something that happened at work' before she tragically disappeared.
'Police are looking through the camera footage where Alison works so they can observe her on a day-to-day basis in the days before she disappeared,' the family friend said.
'Alison’s mother has been told that she was upset about something to do with work so police are looking for clues on the (CCTV) tapes.'
An employee of the bar denied that any altercation unfolded outside the bar that night but conceded her disappearance was strange given the size of the the town.
'There are so many rumours and stories floating around about what happened to Alison right now so it’s pretty weird,' the employee told News Corp.
Whistler RCMP Staff Sergeant Paul Hayes said the search will now focus on the Alpha Lake Park region, with divers and helicopter set to resume their efforts when the weather permits.
Ms Raspa’s nervous friends in Whistler have organised searches of their own, while her friends back home have started Facebook campaigns appealing for information.
