Brendan's testimony, as I read it and in the same chronological order it was presented:
Brendan was getting mail, and heard screaming because you know, it's always better to let a victim who you're about to rape and murder scream as loud as they want so that only a retarded kid nephew can hear and no one else from down the block. Gags are just for sissies.
So of course he hear screaming, because you know, the door was opened
They drank soda
Brendan then went into the room and raped Teresa, sorry, put his penis in her vagina
Then they watched TV
Then Avery stabbed her once in the stomach, then choked her til she was unconcious
Wait, she was still handcuffed to the bed, but Brendan helped Avery tied her up anyways because apparently she was kicking after being stabbed and choked
Then he cut some of her hair off, and set it on a counter
Then Avery told Brendan to cut her throat
Then they uncuffed her, and tied her up
Then they took her outside of the garage where Avery shot her in the head
Or was it Brendan that shot her? "Where did you shoot her?"
Supposedly, Brendan also shot her in the stomach
Wait, he didn't shoot anyone... phew...
Wait, Brendan shot her three times
Brendan helped Avery tied up Teresa's feet, because she was kicking
No wait, she was dead when they tied her up
Then, they took her out to the side of the house
Then, Avery shot her in the head
Or was it Brendan that shot her in the head three times?
Anyways, then, they tossed her in the fire, and covered it with tires and branches
But not before they dragged her into the garage, where Avery put her inside her RAV4 and he may or may not have shot here there
Or, she may have been laying on the garage floor, where he shot her 10 times
Meanwhile, no one else heard any shots
The fire was already burning before Brendan got there, because apparently Avery was planning on burning the body before killing her
Or did he wanted to put her body in the RAV4 to take it to the pit and throw in the water? So confusing...
Wait, now she's shot IN the garage
Wait, in the truck
No, in the garage, then put in the truck
Avery shot her ten times, while she was on the garage floor
Then Avery abandoned dumping her and tossed her body in the fire instead
They moved the body from the garage to the fire by using a creeper
