Police believe Jayme Pasieka was drinking and may have been plotting an attack two weeks ago when a stabbing rampage at the Loblaw warehouse ended with two workers dead and four others wounded, court documents show.

Shortly after 1 p.m. Friday, Feb. 28th, Pasieka donned a bullet-proof vest and armed himself with two knives before heading out the door for work, police say in a warrant application.

On his way stopped at a military surplus store in West Edmonton Mall to buy two larger 'military-style' knives. 

"It is possible that he was formulating thoughts about harming others here as he left home and went to the Supply Sergeant and purchased these two knives," said Det. Andre Francois.

"Through these specific actions, Pasieka appeared goal-oriented and purposeful," he said.

The attacks started shortly after Pasieka arrived to start his shift at 2 p.m., police said.

The documents show that Francois believed the two men stabbed fatally, Thierno Bah and Fitzroy Harris, were among the first to be stabbed, followed by Mahmoud Ayesh whose 12 wounds included one stab wound that punctured a lung and a bite to his knee.

Two people responding to cries for help, Axamed Maxamad and Abdelfetteh Aouachri, were stabbed at and slashed next.

As Pasieka tried to leave the warehouse he encountered co-worker Michael Benti who was frantically calling 911. Benti was stabbed under the jaw. 

All of the injured are expected to recover.

None of the information has been proven in court.

​Pasieka, 29, who faces two counts of first-degree murder, three counts of attempted murder, aggravated assault and possession of an offensive weapon, is scheduled to appear in court on May 5th.
