The Calgary man who was accused of killing his two children and attempting to murder his estranged wife was found guilty in a Calgary court room on Thursday.

James Bing Louie was found guilty of two counts of second-degree murder.

Louie's defense council maintained, throughout the trial, that he didn't comprehend his actions on that day.

Louie was found criminally responsible for the deaths of his children, 13-year-old Jason and 9-year-old Jane.

Ying Tang, Louis' estranged wife, took the stand during the trial and under cross examination, described her unhappiness in her marriage to James Louie.

She told court that Louie appeared to have a split personality in the days leading up to the murder.

Tang told the court that she knew something was wrong on November 27, 2009. She said she called her estranged husband for hours asking to speak to her children.

Tang says she arrived home and the house was pitch black. When she went to her daughter's room she thought the little girl was sleeping. She touched her face and realized she was not.

She dialed 911 on her cell phone and within seconds James had a rope around her neck. She struggled and ended up on the bathroom floor, face down.

At that point, city police burst in and interrupted the altercation. They found the two children dead in the home. Tang survived the terrifying ordeal and was taken to hospital.

Louie admits he killed his two children and tried to kill their mother but pleaded not guilty to the charges.

On Thursday morning, Calgary police issued the following statement on behalf of Ying Tang, the mother of Jason and Jane Louie:

Ever since the brutal murders of my children Jason age 13 and Jane age 9, and my own near-death on November 27, 2009, I have been struggling with pain, sadness and fear. I would not have been able to survive and cope with this tragedy if it wasn't for the generous support that I received around me.

As the trial is closing, I would like to express my eternal gratitude to:

• The 911 dispatcher's quick and clever actions to determine my location for the police service with only an abrupt and distressed phone call from my mobile phone.

• The entire Calgary Police Service, from the constables that saved my life in the evening of November 27, 2009, the homicide lead detective and her team's extremely thorough investigation, to the police chief's absolute supportiveness.

• The Crown counsel team's persistent work in the prosecution of the accused.

• The persistent and vital emotional support of the Calgary Police Service's Victim Assistance Unit.

• The media's respect and understanding of my request for privacy.

• My employers, colleagues, my children's schools, soccer teams, clubs, their families' kind words and demonstration of good deeds.

• The Grief Support Group's providing of a safe, supportive, and healing environment.

• My family and friends' unconditional support, comfort, and sincere affection.

• My psychologist's professional assistance to help me to cope with the tragedy through counseling and psychotherapy.

And sincere thanks to all those who have been unanimously supporting me through prayers, good deeds and other actions.

Let the final tribute to my dear children be a reminder of the importance of life for all of us. If these horrific experiences would help us to make one single good change in our lives, Jane's and Jason's short but sweet lives would be translated into happiness for many others. Their passing through this earth would then be a seed of joy that will multiply over many lives and years.

Hold on to the children that have been entrusted to you. Keep them safe and protect them with all your energy and love.
