A Mississauga community is reeling after a mother was charged with second-degree murder in the death of infant daughter on Wednesday.

Police said the body of Evadne Williams-Scott, 2, was discovered with “obvious signs of trauma” on Tuesday afternoon in a townhouse on Colonial Drive, near The Collegeway and Ridgeway Drive.

A bouquet of roses and a small card that read ‘To Little Angel” marked the crime scene on Wednesday.

Officers had been called to the house on Tuesday on reports of a disturbance. Neighbours reported seeing suspect Teresa Amelia Williams out on her balcony in a tank top with no shoes, screaming profanities.

“Her body was half hanging out the window and she was just like acting hysterical. She was just going off for no reason,” said neighbour Tanya Viens.

Upon arriving at the scene, Acting Insp. Randy Cowan of Peel Regional Police said officers had to subdue the 24-year-old woman with a Taser “due to her heightened state of hysteria.”

At a Wednesday morning news conference, Cowan confirmed that Williams is not known to police.

Attending officers had to force their way into Williams’ townhouse unit, said Cowan. Inside, investigators found the dead body of her daughter.

It’s believed that the victim was her only child.

“Every homicide case is tragic,” said Cowan. “Of course, a two-year-old victim is an innocent victim. It’s especially tragic at this time of year. That certainly exacerbates the situation.

A number of Williams’ neighbours said they did not know the family very well. The pair lived alone in the townhouse unit. It’s believed they moved into the community last summer.

“It’s a shock because we’ve never seen that type of person. We always saw a responsible mom. She always said ‘Hi’ to us,” said neighbour Ian Collins.

Meanwhile the child’s father, Wendell Scott, said his daughter always seemed happy with her mother.

“When she’s around the baby, the baby is fine with her. She’s all happy with the baby,” Scott said.

An autopsy on the child’s body was scheduled to take place Wednesday.

Peel police are encouraging anyone with information about the case to call homicide investigators at 905-453-2121 ext. 3205. Anonymous tips can be left at 1-800-222-TIPS (8477).
