The jury in the attempted murder trial of Ronald Wasser was unable to reach a verdict during their first day of deliberations on Wednesday.

They began their work around 1 p.m., and twice returned to the courtroom with questions for the judge.

But by 8:30 p.m. media were informed the jurors had been sequestered to a hotel for the night and would resume deliberations Thursday morning.

Wasser, 48, of Riverview, is accused of trying to kill his estranged wife, Norma Wasser, 49, with a shotgun last May.

He is also charged with discharging a firearm 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.

On Wednesday morning, Justice Jean-Paul Ouellette, of the Moncton Court of Queen's Bench, spent two hours going over instructions to the jury.

The six women and six men were sent to the jury room at 12:30 pm. for lunch and then began deliberations.

They twice returned to the courtroom with questions for the judge, although it's unclear what they asked.

The week-and-a-half long trial heard testimony from 20 Crown witnesses. The defence did not present any evidence.

The Crown contends Wasser had the opportunity and the motive to try to kill his estranged wife, but the defence argues the evidence is lacking and Wasser should be found not guilty.

Norma Wasser sustained a serious wound to her left arm from a gunshot on May 29, 2013.

The Wassers were going through a divorce at the time and Ronald Wasser had been ordered by the court to be out of the family home by noon on the day of the shooting.
