Random acts of extreme and unprovoked violence will not be tolerated. That's the message from a Calgary judge who sentenced two murderers today.

Chantelle Campbell and Jarod Henry were found guilty by a jury last month in the 2012 Beltline kicking death of John Herrera Garcia, 49.

"This man who came to our country to find peace and security, instead found hatred and brutality," said Justice Ged Hawco when handing down the sentence.

Herrera Garcia was walking home with groceries when he was attacked. He had recently brought his family to Canada from Colombia.

A second-degree murder conviction comes with an automatic life sentence with no chance of parole for at least 10 years. For Campbell, Hawco imposed a 14-year parole ineligibility and 12-years for Henry.

Three people were originally charged with second-degree murder. Last month, a jury acquitted Garrett Smith and found Campbell and Henry guilty.

The attack happened in May 2012; Herrera Garcia died in hospital several months later.

During the trial, both Henry and Smith testified that they believed Herrera Garcia may have kicked their parked car after they yelled an insult at him.

He was pushed to the ground but Smith denied kicking Herrera Garcia.

In a lengthy, tearful apology, Campbell addressed Herrera Garcia's family and apologized, calling her actions "the worst mistake of my life."

"I'm not a cold-blooded murderer," she said. "Please don't hate me."

Crown prosecutor Ken McCaffrey took Smith's apology with a grain of salt.

"Although it was good optics, I'm sorry, I don't accept what she said," he said. "I don't wish her ill. I wish her the best and, hopefully, she'll make better decisions."
