In these types of investigations, the media is hounding people all the time to talk. Journalists can make their careers breaking open a true crime story, they can secure book deals that make their careers. While they do great work and I have a great deal of respect for the press, they don't always act in the victim/LE's best interest. If they hound the family to talk, they encourage any feelings that LE isn't being open enough with the family, they are the ones publishing a "new" story in a big case that is getting national attention. It's that journalist's name on the byline.
Most journalists and outlets will respect LE requests to not publish something or requests to embargo information until a certain date and time. But they also have an interest in breaking news, selling clicks, and getting stories.
Sorry... I know you would like to tie in a journalistic bottom line, and click bait... But, does her father come off as a guy who is going to change course in the middle of the incestiinvest, and be fooled by a reporter..? I just don't get that vibe
