Derrick Todd Lee (November 5, 1968 – January 21, 2016), also known as The Baton Rouge Serial Killer, was an American serial killer. Between 1992 and 2003, Lee murdered seven women in the Baton Rouge area. Prior to his murder charges, Lee had been arrested for stalking women and watching them in their homes. Despite this, he was initially overlooked by police, because they incorrectly believed the killer was white. Lee was linked by DNA tests to the deaths of seven women in the Baton Rouge and Lafayette areas in Louisiana, and in 2004 was convicted, in separate trials, of the murders of Geralyn DeSoto and Charlotte Murray Pace. The Pace trial resulted in a death sentence. Newspapers suggested Lee was responsible for other unsolved murders in the area, but the police lacked DNA evidence to prove these connections. After Lee's arrest, it was discovered that another serial killer, Sean Vincent Gillis, was operating in the Baton Rouge area during the same time as Lee. Lee died on January 21, 2016, of heart disease at a hospital in Louisiana, where he was transported for treatment from Louisiana State Penitentiary, in which he had been awaiting execution. Methods Lee's methods varied with nearly each murder. Similarities between the crimes included the removal of cell phones from the victim's belongings, and a lack of any visible signs of forced entry into the location where the victim was attacked. Two of the victims' bodies were discovered at the Whiskey Bay boat launch, approximately 30 miles west of Baton Rouge, just off Interstate 10. As a result of an inaccurate FBI offender profile and erroneous eyewitness accounts, police originally believed the killer to be white. Police therefore administered thousands of DNA tests to Caucasian men in and around the general area of the murders. Having no leads, police then allowed the now defunct company DNAPrint Genomics to access DNA left at the crime scenes. DNAPrint Genomics generated an ancestry profile indicating that the suspect was 85% African, thus changing the course of the investigation. Police then knew they were searching for a black man for the January 2002 slaying of Geralyn Barr DeSoto. More specific analysis of the DNA evidence found under the fingernails of DeSoto linked Lee to the 21-year-old Addis, Louisiana woman's death.
