A Riverview man accused of trying to kill his soon-to-be ex-wife had been ordered to move out of the family home by the day of the shooting, a judge and jury heard on Monday.

Ronald Bruce Wasser, 48, is charged with attempting to murder Norma Wasser, 49, by discharging a firearm with the intent to kill her at their home on May 29, 2013 — the day after what would have been the couple's 25th wedding anniversary.

He is also charged with discharging a firearm at her with the intent to wound or endanger her life, assault with a weapon, assault causing bodily harm, aggravated assault, and possession of a weapon for a dangerous purpose.

The couple was in the midst of divorce proceedings at the time, Crown prosecutor Annie St. Jacques told the courtroom.

Their marriage had started to unravel in 2007, when Norma Wasser moved to a bedroom in the basement, St. Jacques said.

The couple had minimal contact, then Norma Wasser filed for divorce, she said.

Ronald Wasser had been ordered by the court to move out of their Kerry Court residence by May 29, the day of the shooting, said St. Jacques.

Police were called to the home just after 5:30 a.m., the courtroom heard.

One of the couple's sons heard Norma screaming and found her in bed in a pool of blood, said St. Jacques.

He and another son called 911 and tried to stem the blood flowing from her left arm.

When police arrived, they knocked on Ronald Wasser's bedroom door, but there was no answer. Officers forced the door open and found him in bed.

They asked if he had taken anything. "Pills," he replied.

Police also found a text message Wasser had sent to his mother at 5:40 a.m., which read, "Sorry," the jury heard.

The Crown contends Wasser wanted to commit suicide, but wasn't "going to die alone."

Victim thought she was dreaming

His wife suffered serious injuries she could have died from, said St. Jacques.

Norma Wasser told the courtroom the shot broke her left arm in two places and broke an artery.

She broke down on the stand, recalling what happened that day.

She said she heard a bang and realized her locked bedroom door had been kicked in. She saw Ronald in the doorway, then heard a bang like a shotgun.

She wondered if it was a dream and thought Ronald had missed, but then she felt tremendous pain in her arm, and when she touched it, it was wet, she said.

That's when she started screaming, she told the courtroom.

Defence lawyer Scott Fowler asked Norma if she had told police she didn't see who shot her.

She said she couldn't say with 100 per cent certainty it was Ronald's face, but she recognized his silhouette in her doorway, she said.

A Remington 12-gauge shotgun is among the evidence submitted to the court.

Four weeks have been set aside for the trial before Court of Queen's Bench Justice Jean-Paul Ouellette.

It began last Friday with the jury of six men and six women being selected and given instructions by the judge.

Wasser has been in custody since the incident after being denied bail.
