The bodies of Mr Fowler, 23, from Sydney, and his North Carolina girlfriend Chynna Deese, 24, were found in a ditch on the side of a BC highway.
The RCMP have announced that to assist in the ongoing search for the two suspects wanted in connection to homicides in British Columbia, the Manitoba RCMP's Underwater Recovery Team (URT) will be arriving in Gillam tonight - Saturday, Aug. 3. Gillam is located near its banks.
RCMP searching for two British Columbia murder suspects say they spotted a damaged aluminum boat on the shore of the Nelson River in northern Manitoba.
"Even with this extraordinary effort, we have not had any confirmed sightings of the suspects" since their torched vehicle was found outside Gillam on July 23, said RCMP spokeswoman Jane MacLatchy during a press conference Wednesday.
"It had gone through some rapids and had been significantly damaged", Insp Fiedler told the Globe and Mail.
"We're going to search in the area around where we found this boat just to make sure that there is nobody attached to it, whether that is our subjects or anyone else for that matter". Sightings have been posted to social media before being shared with the RCMP, that has caused delays in the investigation. The small, remote nature of Gillam - it has 1,200 residents and only one road connecting it with the rest of the province - has led to speculation that the suspects may have attempted to escape the area on foot or via boat rather than remain in a setting where they would eventually be identified.
