Louis Ephraim Wilson III was sentenced Friday to life without parole after being convicted of first-degree murder in the bludgeoning death of Tracey Baldwin in May 2007. Baldwin, 38, was attacked and brutally beaten in her home in Chatham Subdivision. An autopsy revealed she had been sexually assaulted, strangled, bound with fishing line and bludgeoned to death. An investigation by the Chatham County Sheriff’s office and the SBI produced DNA, phone records and fraudulent transactions with the victim’s credit cards that tied Wilson to the crime.
