BAKERSFIELD, Calif. -
Lack of DNA evidence doesn't change Christopher Lightsey's status as the primary suspect in the killing of 4-year-old Jessica Martinez in 1990.
In 2008, Lightsey's DNA was swabbed to see if it was a match to DNA found on Martinez's clothes. On Monday, Sept. 24, the District Attorney confirmed the DNA did not match.
Lightsey is on death row for the 1993 murder of cancer patient William Compton, 76.
In several interviews, Lightsey claims he could not have been involved in the Compton or Martinez cases, especially since evidence doesn't point to him.
Officials would not discuss what evidence they have obtained linking Lightsey to the crime because it's still an ongoing investigation.
