The murder and rape of a woman and young girl continue to baffle Cape Coral police decades later.  32 year old Lisa Story and 11 year-old Robin Cornell were killed 20 years ago this week.

The murders were featured on America's Most Wanted twice.  But despite media exposure and clues left behind, including a set of keys and DNA, police have no suspect to match it to.

Trish Routte from SWFL Crime Stoppers helps review the case--as police still search for a suspect.
