Plot Synopsis

HEAR NO EVIL follows the investigations of murders solved using captured-in-the-moment audio evidence, as captured by the victims' families, the perpetrators' friends and investigators. Using authentic audio recordings, first person interviews with family, friends and investigators, along with limited re-creation, HEAR NO EVIL pieces together how the crimes happened -- and how audio recording helped solve them, revealing what really happened and the killers' true motives. Each 60-minute episode features a different crime, including: a home break-in in Little Falls, MN, culminating in a gruesome double-homicide.
