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. >> brewer had stab wounds in his neck and his chest. and then later on after that, i even saw -- i witnessed them stabbing him and taking all his clothes. and at that point 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 doing nothing but the i looked in the dumpster where his face in the duffel bag was moving in and out like he was trying to breathe. 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 by the image.
