The mother and family of stabbing victim Joshua Thomas, 21, were visibly upset as they walked out of the Erie County Courthouse.

"We lost a son, a father, a brother and no matter what it is its not going to bring him back to us," Victim's Mother Gloria Thomas said.

This emotion surfaced just minutes after Erie County Judge William Boller sentenced killer Jawain Wilson, 32, to 20 years behind bars.

"I just want to say I'm sorry," Wilson said.

Both the victim and the defendant were working at the Goodwill Industries Store in Buffalo when they got into an argument and Wilson stabbed Thomas to death. The Defense Attorney Frank Bogulski said there is more to the story.

"At the time of the incident my client was off of his meds. He is diagnosed with Paranoid Schizophrenia. So. when he was approached by his co-worker and bullied he reacted with violence because of his mental illness," Bogulski said.

The judge and the family said there is no excuse. The judge had this to say to Wilson.

"If someone killed your son or father I don't think an apology would be enough," Boller said.
