Lawrence Hong, Kaiti Perras, Jordan Segura, Josh Hunter and Zackariah Rathwell were a group of talented young people with promising futures. On this episode of the Global News podcast Crime Beat, crime reporter Nancy Hixt brings us to Part 2 of her special series, the Brentwood five massacre. What started out as a party to mark the end of classes at the University of Calgary ended in a horrific tragedy. It happened quickly and without warning. In less than a minute the five victims were stabbed in the biggest mass killing in Calgary’s history. Police arrived on the scene less than five minutes after the first call to 911. To add to the complexity of the case, investigators quickly learned the suspect was the son of one of their own. The accused was the 22-year-old son of a veteran, high ranking officer with the Calgary Police Service and would soon be charged with five counts of first-degree murder. But what led to such a horrific and violent attack?  Contact: Twitter: @nancyhixt Facebook: https://www.facebook.com/NancyHixtCrimeBeat/ Email: [email protected]
