Australian DNA Kit Users - Contacted By Police Over Relative Suspect

Did you upload your DNA to a site like Ancestry or 23andMe, then get contacted by police because a relative became a suspect? I'm an Australian documentary-maker looking to speak with people who put their DNA into a consumer genealogy or DNA database — and later found out investigators used it to reach them about a relative under suspicion in a criminal case. I want to hear what that was like: how police approached you, what they asked, how it affected your family, and how you feel now about having uploaded your DNA in the first place. Happy to talk on background or anonymously. DM me and we can find a time. Although I'm ultimately looking to interview people on camera, I'll treat any conversations/ messages as completely confidential.
