The Springfield Police department said Milhon was last seen at a convenience store at 10 p.m. on December 20. She was seen leaving the store, a few miles from where her body was found, in a black vehicle. She contacted family the following day saying she was the victim of a possible assault.

Deputies said Milhon’s body was found outside a home at the corner of State Highway H and Farm Road 88, where crime scene tape could be seen. According to KY3, detectives said they don’t believe Milhon had any connection with people at the home.
