IMHO this is a premeditation case. He was doing google searches the day before he killed her. He strangled her. Preplanning and then premeditation. If BC is guilty (and I believe he is) he should be convicted of 1st degree murder.
And no, I do not think there was any planting of evidence, nor anyone connected with the state's case changing files or changing timestamps, nor do I think his wifi network was hacked. Just throwing that spaghetti against the wall and claiming there could have been if someone who knew how to do something nefarioius had access to it, does not show me there was. As such, I discard all of that nonsense.
