Police in Thunder Bay, Ont., are appealing for help in locating the friends and relatives of a 38-year-old Waterloo woman who died last week in an alleged suicide assisted by her husband.

Police and paramedics responding to an emergency services call in the northern Ontario town found Yanisa Fonteece dead in a motel room on Friday morning, said Chris Adams, a spokesman for the Thunder Bay police service.

The woman's husband had called 911 and was present, Adams said Monday.

Peter Fonteece, 46, has been charged with criminal negligence causing death and assisting a suicide. He made a brief court appearance on Saturday and is scheduled to appear again in court on Tuesday.

Adams said it would be "very useful" for anyone who knew the couple to come forward.

"We are obviously having a challenge contacting family," Adams said.

Police said investigators believe the unemployed Waterloo couple were en route to British Columbia and stopped in the city when their vehicle broke down last Monday.

No information has been released on the possible cause of the woman's death. A postmortem examination in Toronto was done on Saturday, but the results from further medical testing could take several weeks to be known.
