Scott Peterson looks to be aging well on death row at California's San Quentin prison. In a new mugshot, the man convicted of killing his pregnant wife, Laci Peterson, and her unborn son on Christmas Eve 2002, looks much the same as in his last mugshot, taken in 2011, per TMZ. The 45-year-old sports the same short, dark hair, but with a few extra lines visible on his forehead and around his eyes. The photo was taken earlier this month. CBS Sacramento notes convicts are photographed every five years or so, or after a distinct change in appearance. (Last year, Laci's mom recalled the last time she saw her daughter.)
