Officials need the public's help in learning more about Alan Wlimer Sr., the man now suspected of killing three people in the 1980s, two of which were covered in Oxygen's Lovers' Lane Murders. 

Investigators have spent decades puzzling out the Colonial Parkway murders. While the search for answers continues, theories have emerged.  

Between 1986 and 1989, four double homicides occurred on or near the Colonial Parkway in Virginia. A suspect has never been identified in any of the murders.

This Valentine's Day weekend, Oxygen has programming all about the dark side of love, including a two-night special event, "Lover's Lane Murders."
