Investigators say Baker was reported missing from his Shell Point residence on June 27, 1987, by his stepmother, Susan Baker. She told investigators that Paul must have walked out of the house while she was taking a nap.
Officials say it was disclosed that Susan Baker was under the influence of alcohol and drugs at the time of Paul's disappearance, and her story was highly suspicious. Through investigation, it was learned that Paul and his six-year-old sister were physically abused by her on a regular basis. Ultimately, Susan Baker was charged and convicted of assault on the sister.
