MPD Uses Familial DNA to Identify Sexual Assault Suspect

For the second time in the State of Wisconsin’s history, DNA from a relative led to the identification and arrest of a suspect wanted for a sexual assault. Antoine D. Pettis, 20-years-old and from Milwaukee, was charged on November 18 after he was identified by familial DNA and later confessed to the sexual assault of a 101-year-old Milwaukee woman. In an interview with investigators, Pettis admitted to entering the woman’s home near N. 35th Street and W. Florist Avenue around 2:00 a.m. on September 1. Pettis said he went into the home with another suspect with the intention of burglarizing it. When he found nothing that he wanted to steal, Pettis admitted to sexually assaulting the victim and fleeing the scene. Pettis left behind DNA evidence at the scene. On November 13, detectives from MPD’s Sensitive Crimes Division identified Pettis after his DNA revealed familial traits with those of a male relative of his, which was already in a DNA database. Investigators brought Pettis in for questioning at which time he confessed to the crime. The Milwaukee County District Attorney’s Office charged Pettis with burglary, aggravated battery, and sexual assault. If convicted, he faces more than 58 years in prison. Earlier in 2014, Milwaukee Police became the first in the state to use familial DNA to identify a serial rapist, Michael Dixon, who is awaiting trial.
