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 worry about it. he said it's better if you don't know. >> link said that ackerman ordered him to buy some gasoline and bring it back to the apartment. when he returned, things had gotten much 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 off his clothes. and at that point kind of everything 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 carried him out to the dumpster. >> i thought he was dead because he wasn't moving, wasn't doing nothing but the duffel bag 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. i didn't know what to do. i was kind of just taken aback
