crime scene Cold Case Crime Scene, John Koonce Road, Moss Bluff, Calcasieu Parish, Louisiana. Early one Saturday morning in November 2009, the lifeless body of a young woman was found by man riding a bicycle in a roadside ditch. There was no wallet or ID to be found on the scene or on the body, her face was unrecognizable due to blunt force trauma to the head, identification would be difficult and have to be made by other means. During autopsy, a tattoo was identified on the upper torso and found an exact match in a database of prison tattoos kept by the Calcasieu Parish Jail, the local prison— Sierra Gayle Bouzigard, 19 yrs old, had been held for a minor offense and had just been released from the Calcasieu Parish Jail three days prior. Besides identifying Ms. Bouzigard, the information was a lucky break, narrowing the window of her last known whereabouts and contacts to the last 72 hours of he life— all detectives had to do was track down everywhere she went, all the people she came in contact, for three days. A team of detectives set about and reconstructed the last three days of Sierra’s life. At the Crime Lab, evidence found at the scene was matched to fingernail scrapings the coroner took from beneath Sierra’s fingers— a goto source when looking DNA originating from the offender— pointing to a single male suspect. Detectives took this single male profile, this unique DNA signature, compared it against DNA they collected— male and female— in their three day round-up, and ran it through CODIS as well, but not one tested positive, including everyone in a one room house of Mexican immigrants, Sierra’s last known location before she was found dead, bludgeoned, her face unrecognizable, on John Koonce Road. The case went cold, but detectives had a pretty good idea who dunnit, buttressed by that three day window, and where she ended last. Murder’s like this are likely repeat offenders, you don’t kill someone like this just once, you do it again, and again, but there was no match in CODIS, they figured, their perpetrator was Hispanic, that he’d fled to Mexico that night, or shortly thereafter, definitely before they started collecting DNA and testing it against the profile. Six years passed, when a Lab Tech, Monica Quall, working in the forensic lab watched an informational video, called DNA Phenotyping, while eating her lunch one day. DNA Phenotyping, developed by Parabon Nanolabs, produced a genealogical profile, the physical likeness of a person whose DNA it was, including such traits as geographic ancestry, eye and natural hair color, and even produce a sketch, a computer drawn police sketch of what the suspect looks like. Quall's eyes lit up, and she knew exactly the case to apply this on, and called the detectives working on the Bouzigard cold case. The Parabon test was run on the DNA evidence from the crime scene, and the profile and sketch revealed a white male suspect or Northern European ancestry. This lead, gave detectives a new theory for the case, and based on that sketch, the Calcasieu Parish Sheriff's Office received a tip that led them to Blake Anthony Russell, 31. The Sheriff's Office then began surveilling Russell until a DNA sample was secured from an item he discarded. DNA was recovered from this item, and a positive match for the evidence DNA collected at the crime scene was made. Arrested on July 24, 2017, Russel was indicted on one count of second degree murder. One year later Russel was found hanged at the Calcasieu Correctional Center.
