A California judge has approved a request for additional DNA testing on duct tape that was found on the body of Laci Peterson , whose husband was infamously convicted of murdering her and their unborn baby decades ago.

Though the San Mateo County judge on Wednesday approved the request by Scott Petersons defense team, she rejected similar DNA testing requests for more than a dozen other items.

The Los Angeles Innocence Project, a nonprofit that took up Petersons case in January , argued to the court that the tape was found with human DNA on it when it was discovered in 2003 but that the DNA was not of an acceptable quality to generate a profile at the time, according to ABC News .
