Suff began killing in the 1970s and was convicted in the death of his 2-month-old daughter in Texas in 1974 and sentenced to 70 years, but he was paroled in 1984 and moved back to California.

William Lester Suff, 73, was already on death row for a dozen murders in Southern California. Now, he has confessed to killing a 19-year-old woman, shutting a 1986 cold case, officials said.
