Connor's mother, Judy, also spoke to Judge Canady prior to the sentencing. She plead for a short sentence for her son. Judge Canady reminded Connor that he was facing up to life in prison for murdering Singler on February 23.
Singler's older brother, Ryan, said to McCowan, "you're punished for that choice and I hope it's to the fullest extent. You ruined lives."
"You've stolen my brother from me. You have killed and stolen my baby brother from me," said Aryn, Singler's only sister. "That decision not only killed our baby brother, but it killed part of our family."
McCowan was very emotional in court as he addressed his friends and family. He spoke to Singler's family, saying that everyday he wishes he could trade places with Andrew.
"Andrew was such a positive influence on my life and everyday I wish I could trade places with him. To my friends and family, I cannot thank you enough. Please never forget how much I love you all," said McCowan.
Singler's older brother, Matthew, said to Connor, "it's convenient to look for sympathy when you know you're going to be punished."
6 News sat down and spoke with the McCowan family after the hearing.
"I love him and I miss him so much and I know he's looking out for Connor and, you know, if there's anything I could have done differently that night to change all this, I absolutely would go back and do it," said Shay McCowan, Connor's sister.
The McCowan family says they believe their son acted in self-defense and they plan to appeal the charges.
