we don't know the whole story until the case comes to trial. yes, he could be a raving lunatic, or they could have gotten into a fight and a typically nice guy may have accidentally mortally injured his wife, panicked and hid her. although after reading accounts of the family spokesperson who spent a lot of time with JB during the last 8 months he was flabbergasted at how 'normal' JB acted, which i find a bit discomforting, but i won't judge... there are several reasons why people might behave this way, from disassociation to sociopathy. we don't know.
as for shannon, we don't know her personally. but i don't think it's immortalizing an angel to say nice things about her, it's more about respect for the dead. i've read rumors she was an escort, other's have heard JB was into meth. i'm not going to believe any of that until i hear proof.
no one is perfect, i know this will probably get a lot of groans, but i didn't find shannon a 'great' actress, but she seemed like a lovely person and was probably very intelligent and funny. i also found JB unattractive but maybe he isn't photogenic. in the end though, i still feel so incredibly bad for shannon, and am very very sad it turned out this way. as for JB, i don't know his personality, his mental health, his logic... i reserve the right to wait on an opinion during the case. which i hope answers questions. i honestly believe he eventually broke down and confessed personally, but that is my own opinion.
things may have been very tense in the household. accidents happen, people panic. people also are evil and kill out of spite or jealousy. in time we will hopefully have some answers. in the meantime i'm just going to try to keep updated and an open mind.
