Florida fugitive Brian Laundrie’s sister has received numerous death threats — prompting police patrols at her home — ever since he slipped away from authorities, according to a new report.
The threats to Cassie Laundrie Luycx and her husband, James, have included threats about “killing his family and kidnapping his kids” and “messages from random people,” Manatee County Sheriff’s Office records reviewed by WFLA-TV show.

Brian's sister has been probably been the most respectful in this whole mess, and she gets death threats?!?!

Probably good advice to stay away from news cameras as a general rule.
His sister? That's absolutely nuts. She hasn't had any involvement with this at all and has been much more helpful than the parents. The people who made those threats should be locked up. Even if they had made them to the parents, that's not how you do things.
