Police Scanner Audio From Greyhound Bus Beheading Scene

Doing A Bit Of My Own Investigating Into The Greyhound Stabbing, I Came Across This Short Clip. The Attacker Was Still On The Bus. Apparently He Ended Up With A Pair Of Scissors, And Aside From Chopping The Victim Up, Also Ate Some Of The Flesh. Details I Havent Read About Elsewhere. Go Greyhound?
