>>9536642Nancy turned to alcohol and sedatives in order to cope with Benoit's abuse and a strained homelife. Chris was on the edge and saw her drinking, flipped the fuck out and felt the need to punish her by restraining and choking her. She didn't resist much from the drunken stupor and Benoit went too far, killing her.
Once he realized what he had done, he had a full-on schizo meltdown. He got drunk or high himself, which is why he sounded groggy on the phone. He killed his son and put bibles next to his and Nancy's bodies. After all that he killed himself.
Sad story.
