​Karissa Dow met the man known as "Boss" in Lloydminster in 2011. They became romantically involved and had a baby girl. 

He was a leader in the White Boy Posse, an Alberta street gang that dealt drugs and whose members meted out violent retribution against anyone who got in their way.

The price of the gang life

Dow testified at the first-degree murder trial of Randy O'Hagan. He's accused of fatally shooting Saskatoon mother Lorry Santos in 2012.

The story emerging through various witnesses is that Santos, married with four children, died when two gang members — ordered to kill a man who had left the gang — went to the wrong Saskatoon house.

Dow said that people simply didn't leave the gang.

"They would either beat them up or kill them," she said.

Such was the case when a friend of the Boss left the gang and moved to Saskatoon, she said.

The man, known as TJ, vanished after taking clothing, marijuana and a gun from Dow's boyfriend.

A murder, and then fast food

This act triggered the sequence of events that led to the fatal shooting of Lorry Santos.

Gang members tracked TJ to Saskatoon. Other witnesses said they came to the city from Alberta with the express intent of killing.

Instead, they went to the wrong house and shot Lorry Santos.

After the shooting, "they got takeout from McDonalds and sat around talking" and then drove back to Alberta, Dow said.

The trial continues.
