LOS ANGELES (CBS/AP) Los Angeles detectives believe that suspected "Grim Sleeper" serial killer, Lonnie Franklin Jr., never took the break in his crimes that his nickname suggests.
Franklin has been charged with killing 10 women from 1985 to 1988 and from 2002 to 2007. The 14-year pause led to the nickname "Grim Sleeper." He has pleaded not guilty.
But Detective Dennis Kilcoyne said Franklin might also be responsible for the deaths of two women whose bodies were found in Los Angeles in the 1990s. No charges have been filed in those cases.
"I don't think there is a gap," Kilcoyne said. "He was here, he was active. I don't think you stop one day, take a 14-year vacation and then start up again."
Kilcoyne disclosed few details about the new cases, but said the bodies were found in the same general area as other victims - within a few miles of Franklin's mint-green stucco home just south of downtown Los Angeles.
According to investigators, victims of the "Grim Sleeper" were shot, strangled or both, usually after some kind of sexual contact. Several of the victims were prostitutes.
Following Franklin's arrest in July, the LAPD released about 180 photos of women whose pictures were found at his home and in his garage.
According to police, 72 women have been identified and ruled out as victims and four new missing person cases have been opened as a result of the photographs going public.
The women in the two additional homicide cases were not found in the photos.
Kilcyone said detectives still have to identify about 62 women depicted in the photos.
