Jefferson County authorities are following up on a lead in the unsolved slayings of two teens at a sandwich shop last year.

A segment about the Valentine's Day slayings of Nicholas Kunselman and Stephanie Hart Grizzell aired on "America's Most Wanted" over the weekend.

Investigators have said very little about the killings but are looking for a young man who was seen near the shop on the night of the attack.

A detective with the Charleston, W.Va., Police Department called after seeing the show and said that a man in custody there looks very similar to the sketch of the Colorado suspect.

Jefferson County investigators said that they're taking the lead seriously and will try to determine if the suspect was in Colorado around the time of the killings.

Investigators said the TV program also generated more than 45 other tips in the case.

The original case attracted widespread attention because both of the victims were from nearby Columbine High School.
