What if someone you love turns out to be a murderer?
About Someone You Thought You Knew
We all wonder if we truly know the people close to us—our partner, family members, friends. But what if we don’t really know someone at all, and they are, instead, a murderer? That’s the scary premise of Someone You Thought You Knew.
This true crime show consists of the usual elements—narration, re-creations, excerpts from police interviews, and testimonials from victims’ families and friends, who share their stories and reveal their surprise at finding out who their loved ones really are.
About half of the cases appear on other shows, such as Dateline, and the presentation is pretty typical of most true crime shows, so if you’re looking for something new and different, skip this one.
