All of Indiana serial killer's victims could be identified as renewed investigative push plays out in laboratories

Decades after investigators unearthed thousands of human bones and bone fragments on a suspected Indiana serial killer's property, a renewed quest is playing out in laboratories to solve a long-running mystery: Who were they?

A new team working to identify the unknown dead says the key to their success will be getting relatives of men who vanished between the mid-1980s and the mid-1990s to provide samples of their own DNA.

Those samples can then be screened against DNA profiles scientists are extracting from the remains, which were found starting in 1996 on Herbert Baumeister's sprawling suburban Indianapolis property.
