Neighbours of the city's latest homicide victim say they heard an early morning fight that almost knocked pictures off their bedroom wall.

"We heard a lot of rolling around and banging on the walls. And the pictures were moving," Jack Jardine told CTV News on Tuesday. "This is exactly at 5 o'clock in the morning (on Monday) … It went on for a minute or so, then it stopped."

Helen Jardine said they heard nothing the rest of the day.

Then at 4 p.m., "a young girl was outside on the balcony screaming, 'My sister, my sister' -- blood-curdling screams. So she must have come home and found her sister," she said.

Police were called to the Harding Avenue building at 4:35 p.m., where they discovered a woman dead in a first-floor unit. Friends had become worried after they couldn't reach the woman.

Police have identified the victim as Lucita Charles, 28, of Toronto. She was born in St. Lucia and hoped to become a teacher some day. They said she was "suffering from obvious trauma."

An autopsy is yet to be scheduled, but unofficial accounts say the woman had been stabbed. She is the city's 18th homicide victim of 2010.

Residents of the building say Charles is the mother of a disabled son, a seven-year-old who has cerebral palsy. They describe her as a kind, loving woman. However, they did say she did appear very upset the day before her death.

Someone put her son on the Wheel-Trans bus on Monday morning to send him to school. Police would like to know who.

Police say Patrick Kirk Barrett, 39, of Toronto is wanted for second-degree murder in connection with Charles' death. He is reportedly Charles' boyfriend.

Police say Barrett is believed to be travelling toward Montreal, or is already in the city, and is driving an orange 2009 Kia Rio with Ontario licence plate BERR 171.

They describe him as being black, 6'1" with a medium build. Police would like anyone with information to contact them at 416-808-7400, Crime Stoppers at 416-222-TIPS (8477), at www.222tips.com, or by texting TOR and a message to CRIMES (274637).
