EDMONTON -- Police in Edmonton have laid murder charges against a man arrested after a stabbing rampage at a grocery warehouse.

Jayme Pasieka, 29, from Edmonton, faces two counts of first degree murder, two counts of attempted murder, aggravated assault and two counts of possession of an offensive weapon.

Pasieka was arrested Friday after a man with a knife in each hand and wearing a military-style vest burst into the Loblaws warehouse during shift-change and started stabbing people throughout the complex.

Fitzroy Harris, 50, and Thierno Bah, 41, both died. Four others were injured.

Police say they searched the suspect's house on Saturday, but aren't releasing details of what they found.

Pasieka's first court appearance is scheduled for Monday morning.
