Jesperson was arrested on March 30, 1995, for the murder of Winningham. He had been questioned by police a week before, but they had no grounds to arrest him after he refused to talk. In the days following, Jesperson decided that he was certainly going to be arrested, and after two suicide attempts, he turned himself in hoping it would result in leniency during his sentencing. While in custody, Jesperson began revealing details of his killings and making claims of many others, most of which he later recanted. Also, a few days before his arrest, he wrote a letter to his brother. In it, he confessed to having killed eight people over the course of five years. This led police agencies in several states across the country to reopen old cases, many of which were found to be possible victims of Jesperson.
