John Brittain has been charged following a shooting spree in Penticton that claimed four lives on Monday, the BC Prosecution Service has confirmed.
Brittain has been charged with three counts of first-degree murder and one count of second-degree murder.
The incident prompted a massive police response, in which officers asked people to stay out of a large area of downtown Penticton.

RCMP Supt. Ted De Jager said the victims were two men and two women in their 60s and 70s.
He said the victims and the shooter knew one another. Police have not identified any of the victims, but family members have identified one of them as Penticton resident Rudi Winter.
Winter’s nephew said his uncle may have been killed because of a grudge by a former neighbour.
Neighbours have confirmed the other victims are Susan and Barry Wonch, and Darlene Knippelberg.
The City of Penticton confirmed Tuesday that Brittain was an employee with the city from 2011 to 2016.
Penticton Mayor John Vassilaki said Brittain worked for several years in the city’s engineering department.

“He was a gentle man. He did his job well,” said Vassilaki, who was on city council when Brittain worked for the city.
“Other than that I couldn’t tell you anything more about their personal lives or anything like that.”
