Alberta Murder-Suicide Survivor Set For Surgery

The lone survivor of the murder-suicide in rural Alberta last week is set to undergo surgery on Monday in Calgary.

Shayna Conway, a 21-year-old from P.E.I., was shot numerous times with a 9-mm handgun early Thursday morning on the highway outside Claresholm when Derek Jensen, 21, opened fire on her and her friends.

As Conway is treated at the Foothills hospital in Calgary, Conway's family and friends are rallying around her.

Rebecca Sanderson, who worked with Conway at a juice bar in Charlottetown Mall, said she and her co-workers are donating their tips to help with her recovery.

“We just want to show her how much we love her and that we all care for her. And we're all praying for her and we hope she has a speedy quick recovery,” Sanderson said.

Mitchell MacLean, 20, Tanner Craswell, 22, baseball players also from P.E.I. but who were living in Lethbridge, and Tabitha Stepple, 22, were all killed in last Thursday's attack.

The gunman, Stepple’s former boyfriend, then killed himself.

The shooting rampage happened at about 3 a.m. MT on Thursday after Jensen slammed into an SUV on Highway 2.

Conway, accompanied by Stepple, was driving Craswell and MacLean from Lethbridge to Calgary to catch a flight home to P.E.I. for the holidays.

Jensen had followed the four friends from Lethbridge, catching up with their vehicle 1.5 kilometres north of Claresholm.

After the shootings, Conway was able to call for help. She was taken to Claresholm Hospital with life-threatening injuries and later flown to Calgary, where she is expected to make a full recovery.
