Melissa Ivy Chaboyer was a 35-year-old Métis single mother and foster parent living in Thompson, Manitoba, when she was killed during an overnight taxi shift in the early morning of November 26, 2005. She worked part time driving a white North Star taxi, cab number 302, among other jobs to support her family.

Shortly after midnight on November 26, Chaboyer was dispatched to the Thompson Arena and later told her dispatcher she would stop at the Ramada-Burntwood Hotel. Investigators believe she had two passengers in her cab and that, while driving into the parking area behind the City Centre Mall, she was attacked, stabbed to death, and left outside her taxi. The two people believed responsible ran east toward the Eastwood area and have never been publicly identified.

The killing prompted a community vigil, temporary suspension of taxi service, and a 2006 city rule requiring cameras in taxis. No arrests, charges, trials, or convictions have been publicly reported; Manitoba Crime Stoppers lists the case as unsolved and RCMP continue to investigate.

If anyone knew Melissa, saw activity around the City Centre Mall parking area that night, or has other information, please come forward.
