Given that LE returned the phone to Austin's family and said that they weren't going to investigate further since there was no open criminal matter, I don't think it's surprising/strange that Austin's family is trying to get the information themselves rather than waiting for/relying on LE who has indicated that they don't want the phone. I don't think Austin's family has implied that if LE did want the phone/would agree to use their best efforts to get the information off it, that they wouldn't cooperate. Also, since I personally think it's clear there wasn't any criminal activity here, there's no chain of custody issue or any other reason why it matters who retrieves the data. I totally understand that Perry's family may be frustrated with LE and, perhaps, with Austin's family for not pushing the issue with them, but I actually think they're more likely to get the information they actually want if Austin's family proceeds as they are.
