As the family of murdered kansas teen Kelsey Smith prepares to say their final goodbyes -- another family wonders if their missing teen has a Kelsey connection.

17-year-old Kara Kopetsky of Belton, Missouri has been missing since May 4.

Although they haven't found anything yet that leads them to believe the cases are related -- investigators have not ruled it out.

26-year-old Edwin Hall is charged with Smith's murder.

Police are working to see if he could have had anything to do with the Kopetsky disappearance.

Missing Missouri teen Kara Kopetsky and murder victim Kelsey Smith did not know each other.

But their similar appearance -- and the fact that Smith's body was found only six miles from Kopetsky's home -- have led some to speculate whether they met the same fate.

When it was announced a body had been found last week-- the Kopetskys feared the worst...but it was Smith's body that was found.

Now, Belton and Overland Park police are working together to look for connections.

The funeral for Kelsey Smith is set for Tuesday afternoon in Leawood, Kansas.
