UPDATE: Killer's blood not found in national database

MISHAWAKA, Ind. -- It's back to square one for the Mishawaka Police Department.

DNA from the scene of a recent homicide was not found in a national database.

This means the person responsible for killing Lois Hickey is still a step ahead of investigators.

Officers found the 84-year-old dead in her East Donaldson avenue home, in late December.

Last week, they announced the killer's blood was found at the scene.
