Sources: 'Person of interest' questioned in BTK case
Authorities waiting on DNA test results
Friday, February 25, 2005 Posted: 11:36 PM EST (CNN) -- Authorities questioned a "person of interest" in the BTK killer investigation Friday, and converged on a home in Park City, Kansas, just outside Wichita, sources told CNN.
CNN affiliate KAKE, a Wichita station that the killer has sent letters to in the past, said authorities were awaiting results of DNA tests to see whether they could be linked to the case.
The killer calls himself BTK, for "bind, torture and kill," a pattern he has followed with most of his victims.
Sources said the person of interest was questioned for several hours Friday, and that they were growing increasingly confident that the 30-year investigation may be nearing an end.
