On the third day of the trial for the mother charged with two counts of second-degree murder in the deaths of her two sons, two neighbours took the stand; one saying the accused was a "very good mother."

"She was great with her kids. Very attentive," Marless Litzenberger told the court Wednesday.

The two neighbours who testified Wednesday said Allyson was a caring and attentive mother, but became depressed during a bitter separation in late 2009.

"I could see it in her mannerisms. She was sad," Litzenberger said. "She was not herself."

On Tuesday, the former husband of the accused, Curtis McConnell, describing for the court a ‘horrific' scene in February of 2010.

He discovered his two young children, 2-year-old Connor and 10-month-old Jayden, drowned in the bathtub of the family home in Millet – shortly after police contacted him following an apparent suicide attempt by his estranged wife.

He told court inside the bathroom he found the bodies of his children.

"I just dropped to my knees," Curtis McConnell said through tears. "I reached into the water, and the water was so cold.

"I could feel something there; I had to pull them out."

During his testimony, the father told court his former wife ‘possessed a lot of hate and anger', and said she deliberately left her wedding ring on the toilet, and left the bodies of the children for him to find in the bathroom of the family home.

The court also heard Curtis has since filed a $940,000 civil suit against his former wife.

It's believed that shortly after the accused was served with the civil suit, she attempted suicide while she was a patient at Alberta Hospital.

Curtis' mother Audrey also took the stand Tuesday, and described her former daughter-in-law as a good mother, who became angry and upset as her marriage began to erode.

In an agreed statement of fact presented Monday, the accused admitted to drowning her two sons in the family's bathtub, but has pleaded not guilty to two counts of second-degree murder.

On Thursday, the Medical Examiner who examined the autopsies will testify. Allyson's lawyer will then call up his witnesses.

The trial is expected to wrap up at the end of next week.
