New forensic DNA analysis that can create an eerily accurate image of an unknown individual helped cops in Texas solve a year-old murder mystery. Ryan Riggs, 21, is charged with capital murder for the killing of Chantay Blankinship, 25, in May 2016. The man gave confessions to his local church and the Brown County Sheriff’s Office on Wednesday after predictive DNA imaging released Nov. 8 breathed new life into law enforcement’s investigation.
