MISSING HARMONY MONTGOMERY: TIMELINE OF EVENTS

When police discovered in December that Harmony had not attended school in the two years her drug-addicted, felon of a father held full custody, they began a search for both father and daughter.

They found Adam Montgomery living out of a car with Small on Harvell Street on Dec. 31.

After police questioned Montgomery, they alleged he gave them contradictory statements – including first claiming to have recently spoken to Harmony and then backtracking to claim that the last time he saw Harmony was when her biological mother picked her up, sometime around Thanksgiving 2019.

Then he allegedly stopped answering questions and told investigators, "I have nothing else to say … If I’m not under arrest, I’m leaving."

He was arrested four days later, and Harmony remains missing.

Small told investigators that she was aware Adam Montgomery had three children with Kayla but that her boyfriend had never mentioned Harmony, who came from a prior relationship. Small was not arrested in connection with Harmony’s disappearance.
