Charlotte Lily Sauerwin, 24, was last seen on the evening of August 5, 1988, at a laundromat in Walker, Louisiana, speaking with an unidentified man. The next morning her fiancé found her car abandoned on the wooded lot where they planned to build a home; her body was discovered nearby. The case was investigated as a robbery and homicide but went cold for years.

Twenty-two years after the killing, DNA evidence linked the case to Roy Melanson, then serving in a Colorado prison for a separate homicide. Detectives traveled to question the inmate, who was 73 at the time and was reported as evasive and uncooperative. The DNA connection gave investigators a name tied to Charlotte’s murder and raised concerns because Melanson was suspected in other killings; the Colorado victim was also found in a remote, wooded area.

What information might help establish Melanson’s movements around Walker in August 1988, or identify the man seen with Charlotte at the laundromat?
