Police are looking into whether a suspect in the killings of four women in California also killed three little girls in New York state.
Seventy-seven-year-old Joseph Naso is accused of murdering the four women from 1977 to 1994. Authorities call the killings the "Double Initial Murders" because the first name of each victim begins with the same letter as her last name.
Police in New York state say they haven't determined who abducted, raped and killed a 10-year-old and two 11-year-old girls in the Rochester area in the early 1970s. But their first names begin with the same letter as their last names as well, and one girl has the same name as one of the victims in California.
A separate task force is looking into whether there are any cold cases linked to Naso, who was arrested this week in the California cases.
Authorities say Naso once lived in the Rochester, N.Y., area and traveled between there and the West in the early 1970s, but they've found no other evidence tying him to the cases.
