L.A. has so many serial killers you stumble over them

The plan worked.

Just not in the way Kilcoyne had intended.

In late March, the California Department of Justice's DNA laboratory jolted LAPD detectives with news that the saliva collected from 72-year-old John Floyd Thomas Jr., one of the sex offenders contacted by Webb's officers, matched genetic evidence found at the crime scenes of two Los Angeles women raped and killed in the 1970s. Soon after, Thomas was tied by DNA to three more slayings. Details from those cases matched dozens of other unsolved murders and rapes. The women, however, had been older and white, not black and young.

And Thomas' DNA didn't match the man Kilcoyne was hunting.

In looking for one serial killer, the LAPD believes it has stumbled upon another.
