Prejudicial. nancy, it s fascinating, we are learning a lot more since this suspect was taken into custody, including his drug habits. listen here. claim kohberger develops anger issues, even putting one friend in a head lock leading that friend to cut ties. he says he only sees that side when kohberger is drinking. when he got drunk, he was rowdy. they allege alcohol use turns to drug abuse and kohberger is hooked on heroin. sandra: how big a part of all of this were his drug and alcohol habits, nancy? well, according to some, he went clean, stone cold sober. i don t know if that s true, but i think we will find out as the evidence unfolds. another very disturbing thing, possibly even more problematic, to me, it definitely is more problematic, is his frustration and anger towards women.
