I think it would matter. The person who suffocated Alanna would charged with 1st degree murder. The other person would be charged with something else, depending on what he did and what exactly happened. But I don't think they could charge them both with 1st degree of murder unless they had proof that they both actually murdered Alanna. LE would need to determine who did what.
But TH is charged with it. They must have evidence to charge him. If there were an accomplice to the murder......ugh. but they must have evidence at least TH murdered her.
Im so sickened thinking about this!
Was there an accomplice in her murder???
