Police tape at the scene of Winnipeg's 12th homicide of 2010. (James Turner/CBC)A multiple stabbing early Saturday left a 62-year-old man dead and a teenage girl wounded, Winnipeg police report.

Mary Ellen Thomas, 30, is charged with second-degree murder, aggravated assault and several counts of failing to comply with a recognizance order.

The dead man, Michael Allan, had just met a woman earlier that night and taken her to a residence at 851 Nassau St., where they got into an argument and the stabbing occurred, police said.

The alleged attacker later went to a convenience store at Osborne Street and Morley Avenue, near where an 18-year-old woman was stabbed several times, police said. She was treated in hospital and released.

The dead man's brother-in-law, Mervin Forbister, said Allan lived on a disability pension after contracting a respiratory illness that severely affected his health.

"Alcoholism devastated his life," he said. "And it's so tragic because he was brilliant — he was university-educated and a great guy in a lot of ways, but he just couldn't fight the bottle."

Forbister said police told him Allan was beaten, pushed down some stairs and stabbed after an argument over money.

Forbister said neighbours had called 911 around midnight after hearing a dispute at Allan's home, but police did not arrive until at least 5 a.m. because of violence in other parts of the city.

"The neighbour called because the fight was going on around midnight. The police didn't arrive at the house until five in the morning ... that's what the [homicide detective] said, anyways. Because the night was just hopping with bad things."

The 18-year-old near the convenience store was stabbed around 2:15 a.m.

Allan was Winnipeg's 12th homicide victim of 2010.
