Carol Caswell, Lisa Snyder, and Sheila Holmes were forever connected when their names surfaced during the interrogation of a suspect who would later be charged and convicted in one of their murders. That same individual remains the primary suspect in at least one of the two other cases, but it’s been decades since their violent, senseless deaths, and charges have yet to be filed against anyone. When will their families finally get the answers and justice they’ve been waiting for?

• If you have any information that could help bring answers to the families of Sheila Holmes and Lisa Snyder, please report it to the New Hampshire State Police Cold Case Unit using the tip form.

When a 12-year-old girl disappeared from her home on a summer night in 1988, police took her father’s word that she’d run away just as she had more than once before. But more than 30 years later, there’s still no sign of the missing girl and her father’s story just isn’t adding up.
