The police report states that Baum and his live-in girlfriend were first contacted by police on Jan. 9.
Baum and his girlfriend said he had not heard from the missing teens, the police report states, but a search warrant allowed law enforcement to obtain a string of Facebook messages between the girlfriend and Powell on the day the teens went missing, showing that Powell had agreed to meet at the girlfriend's house.
The girlfriend told police Powell had never arrived at her house that night, the police report states, but she later told police that the two teens had arrived at the house past midnight on Dec. 30, smoked marijuana, then left.
The girlfriend was interviewed by police again in March, when she told police that Baum later told her he knew the teens had come over to the house, and he had told her not to have male guests over and that "it was too bad, because he had never killed anyone innocent before."
The girlfriend told police that their shower smelled strongly of bleach, and that on New Year's Eve, Baum burned some stuff in a barrel that smelled like bleach and the flames were green, according to the police report.
The girlfriend also told police that Baum told her that he made Powell suffer, but that he felt bad about Otteson and made it "quick and painless."
