A Canada-wide warrant has been issued for the fourth boy accused of attempting to kill a woman in Westlock County.

On September 7, RCMP were called to the Long Island Lake RV Park and found an 18-year-old woman suffering from serious life-threatening injuries. She survived.

RCMP have arrested and charged three Edmonton boys, two 16-year-olds and one 17-year-old, with attempted murder, robbery and aggravated assault.

Police are still looking for a second 17-year-old boy.

In October, the RCMP said a warrant had been issued for the young man’s arrest.

This mandate is now across Canada.

The names of the four cannot be released because they are minors under the Youth Justice Act.

Police are also continuing to search for the woman’s vehicle, a green 2010 Mini Cooper with Alberta license plate CPL-5715, which was stolen during the attempted murder.

“Alberta RCMP have dedicated a large number of investigators to quickly resolve this priority investigation,” said State Sgt. Jeff Sehn in a press release. “It is clear that, given the young people’s age, they must receive assistance to avoid capture.

“Those who provide assistance may face criminal charges, including, but not limited to, obstruction of justice and parties to a crime.”

Anyone with information is asked to contact Westlock RCMP at 780-349-4492 or Crime Stoppers by phone at 1-800-222-8477 or online.
