Melissa claims that before her stepdaughter, Karlie, went missing in October 2018, she admitted to smoking marijuana and was acting “very strange.” She says she stayed up with Karlie most of the night in her room and fell asleep there. When she woke up, says Melissa, Karlie had vanished.

“I believe my daughter had a drug overdose,” says Karlie’s mother, Lindsay, adding, “And I believe it because she was asking for help.”

Lindsay claims she heard Karlie ask Melissa to call 9-1-1 in an audio recording that Melissa made of the teen the night before she vanished. Melissa denies that that is what the teen asked of her.
