Key takeaways from an AP investigation into how police failed to stop a serial killer

DeAngelo Martin killed four women and raped two others over a 16-month span before he was captured. Only now, a year after Martin was sent to prison, is it clear that police failed repeatedly to follow up on leads or take investigative steps that may have averted the killing spree, despite receiving repeated warnings that Martin was a violent predator, an Associated Press investigation has found. DeAngelo Martin lured four women in 2018 and 2019 into vacant homes and murdered them, leaving their nude or partially clothed corpses amid cheap booze pints, crumbling walls and hypodermic needles.
