The man charged with 10 murders in the "Grim Sleeper" serial killings has now been linked to additional deaths, a law enforcement official said.
The official, who spoke on condition of anonymity because the investigation is ongoing, said Friday that police had connected Lonnie Franklin Jr. to the killings.
The official did not specify how many other people Franklin is connected to, but the Los Angeles Times reported the number as six, bringing to 16 the total number of killings authorities have linked him to.
Three of the six new victims have been linked to Franklin through physical evidence, including ballistics and DNA, the Times reports.
Franklin's link to the other three murders is more circumstantial. Authorities connect two of the victims to Franklin because their possessions were discovered at his house.The third victim was tied to him as well through a 911 call reporting the location of the body. The call was allegedly placed by Franklin himself, the Times reports.
Franklin has already pleaded not guilty to 10 murders and one count of attempted murder. Most of the victims linked to the "Grim Sleeper" were found in alleyways within a few miles of Franklin's home.
Franklin, a mechanic, was arrested in July 2010.
