When five-year-old Harmony Montgomery vanished in 2019, nobody reported her disappearance for almost two years. Officers were worried that her father, Adam Montgomery, killed her, concealed her body and repeatedly moved her remains before disposing of them in an unknown location... and in 2024, they realized they were right. He was convicted of second-degree murder, assault, abuse of a corpse, falsifying evidence and witness tampering. However, in June 2026, the New Hampshire Supreme Court overturned his murder conviction on procedural grounds. Harmony’s remains have never been found, leaving her tragic case still technically unresolved to this day. 🔴 Try my Classified Coffee! - https://bit.ly/3PrY9CS ➤ Patreon: https://www.patreon.com/coffeehousecrime ➤ Instagram: https://www.instagram.com/coffeehousecrime/ ➤ Twitter: https://twitter.com/coffeehcrime ➤ Facebook: https://www.facebook.com/coffeehousecrime ➤ Animated Background by Featherwax Studio: https://featherwax.com DISCLAIMER: Great effort is made to ensure all materials in Coffeehouse Crime's videos fall within the guidelines of fair use.
