Los Angeles police say they may have captured the most prolific serial killer in city history.
They say he's suspected of killing as many as 30 women over a period of decades. The 72-year-old suspect has been charged with two murders, and the Los Angeles Times reports he may be tied to many more.
The break in the cold case came when the suspect John Thomas gave a DNA sample as part of an effort to build an offender database. The sample reportedly matches DNA found at crime scenes of the 1970s and 1980s.
Detectives say the suspect may be tied to two waves of killings. They include attacks by the so-called "Westside Rapist," who preyed on dozens of elderly women who lived alone.
The suspect has worked for years as an insurance claims adjuster. He's being held in county jail and could not be reached for comment.
