Joch Pouk Charged In Deadly Attack On Lukas Strasser-Hird

CALGARY - A third person has been charged in the death of a man who Calgary police say may have been swarmed by up to 15 people.

Police say 18-year-old Lukas Strasser-Hird died of stab wounds last weekend.

Officers believe he was involved in two fights prior to his death.

Detectives say they believe others may have been involved in Strasser-Hird's fatal beating and are hoping anyone with information will come forward.

Joch Pouk, who is 20, was charged with second-degree murder on Thursday.

Earlier this week, Nathan Paul Gervais, who is 18, was charged with first-degree murder and Franz Emir Cabrera, who is 19, was charged with second-degree murder.
