When two teens are found fatally shot inside a sandwich shop just months after surviving the Columbine High School massacre, the Valentine's Day double homicide shocks their community.

Investigators offer a major reward for information in hopes of solving a cold case in this episode of Last Seen Alive.

Thanks for listening to Last Seen Alive. I'm your host, Leah, crime analyst by day, and true crime storyteller by night.

And as always, I'm your co-s, Scott. This is an extra mini episode that we're airing on the anniversary of this case.

It'll be shorter than our typical episodes, but we wanted to cover this story because it seems highly solvable. With the right tip, investigators could potentially finally close

this case. Not only that, but recently, an enormous reward, $100,000, has been offered for

information that leads to resolution in this case. So please, if you know anything,

let investigators know. We'll provide tip reporting information at the conclusion of this episode,

as always. Nicholas Consulman, who went by Nick and Stephanie Hart Griselle, were last seen alive

on February 13, 2000. They were 15 and 16 years old at the time, respectively, and they lived

friends since they'd attended middle school together, and as high schoolers, they'd begun dating.

Their parents and others who knew them described them as a happy young couple, but it had

not been a happy event that had drawn them together, forging a more intimate bond from their

years-long friendship. Listeners of a certain age, of the millennial generation, like us, Scott, or

older, may recall that Littleton, Colorado had been in the national spotlight just the year before in 1999.

That's because Littleton is where Columbine High School is located and the now infamous Columbine

High School massacre had occurred in April of 1999, so just 10 months prior to the case we're

discussing today. Stephanie and Nick were students at Columbine High School and had been present on the day of the massacre.

Neither of them had been physically injured in the shooting, but as one can easily imagine,

it had been incredibly traumatic for them, just as it had for all of the survivors.

But fortunately, Nick and Stephanie had had good friends to lean on for support like each other.
