The family of Tina Mae Eisnor say they finally have closure after her estranged husband was found guilty of first-degree murder in her death.

Wayne Paul Eisnor shot and killed his wife in the parking lot of a New Germany grocery store in June 2010. Eisnor also suffered a self-inflicted gunshot wound to the head and claims to have no memory of the incident.

'It is beyond my comprehension how anyone could show such contempt for human life' - Justice Glenn MacDougall

The CBC's Blair Rhodes said the courtroom was full and silent just before the jury entered. More than a dozen members of the victim's family were there. 

Just before the verdict was read, Justice Glenn MacDougall addressed the tense courtroom and warned them to "try as best you can to maintain your composure. Try not to let your emotions get the better of you."

Eisnor sat on the prisoner's bench on the side of the courtroom, flanked by sheriffs as the verdict was read.

There was a quiet cheer in the courtroom, which was immediately shushed by sheriffs. Members of Tina Eisnor's family cried and hugged. 

First-degree murder comes with an automatic life sentence of 25 years. 

The judge thanked the jury before they were excused, saying they couldn't have done a better job. 

Toll on family

Tina Eisnor's family then had the opportunity to read victim impact statements.

"My heart is broken, and there's no repair," said her sister, Julie Illingworth. "Wayne, I'll never forgive you for what you've done."

"I live with guilt and hate in every breath I take," said Tina Eisnor's sister Trina Wentzell.

The judge addressed Eisnor, calling the killing a "senseless and selfish act."

"It is beyond my comprehension how anyone could show such contempt for human life," said MacDougall. "There could be nothing more cruel or heartless."

In addition to life in prison, Wayne Eisnor must give a DNA sample and faces a lifetime weapons ban.

'Finally justice'

Tina Eisnor's sisters shed tears of joy as they walked out of the courtroom. 

"It was a big weight lifted off the shoulders," said Illingworth. "It's hard to believe we've actually come this far."

Members of the family wore shirts that said "Stop violence against women." They said they hoped other victims of domestic violence heard their story of heartbreak and learned from it.

"When we had a problem, we went to Tina and all of a sudden we don't have Tina no more." 

The family now plays in an annual baseball tournament in Tina Eisnor's memory. They said tomorrow will be a fresh start.

"I'm going to feel like getting up," said Illingworth. "Because we finally got peace for Tina."
