On March 23, 1987, Heidnik and Rivera abducted Agnes Adams. The next day, Rivera convinced Heidnik to let her go, temporarily, so she could visit her family. He drove her to a gas station, and said that he would wait for her there. She walked a block away, and called 9-1-1. The responding officers, noting chafing from chains on her leg, went to the gas station and arrested Heidnik. His purported best friend, Cyril ("Tony") Brown, was also arrested. Brown was released on $50,000 bail and an agreement that he would testify against Heidnik. In part, Brown admitted that he had witnessed Lindsay's death in the basement and he also admitted that he had witnessed Heidnik's dismemberment of her body. Shortly after his arrest in April 1987, Heidnik attempted to hang himself in his jail cell.
