initiated the attack after the victim fell asleep in the bedroom. >> i just heard some banging around. i didn't know exactly what was happening. at one point kasey came out and i was trying to ask what was going on, he was like you don't need to know about it. he said it's better if you don't know. >> link said that ackerman ordered him to buy gasoline and bring it back to the apartment. when he returned, things were worse. >> he had stab wounds in his neck and his chest and then later on after that i witnessed them stabbing him and they had taken all of his clothes. and at that point everything just kind of hit me what they were doing. >> link says he assumed the gasoline would be used to burn brewer's clothes, but instead he claims ackerman and their two other male roommates stuffed brewer inside a duffel bag and stuffed him in a dumpster. >> i thought he was dead because he wasn't moving, he wasn't doing nothing. but then i looked in the duffel bag, and it was moving, in and out. and kasey was starting to pour the gasoline on him. and i kind of just -- i couldn't -- i was just kind of stuck at that moment.
