Cayley Mandadi's 2017 death was initially ruled a homicide, with her boyfriend, Mark Howerton, charged with murder and aggravated sexual assault. A first trial resulted in a mistrial due to a jury unable to reach a unanimous verdict, largely impacted by conflicting expert testimony regarding the cause of Mandadi's injuries. Subsequent investigation by Mandadi's parents yielded crucial evidence, leading to a second trial. Howerton was ultimately acquitted of murder but convicted of aggravated assault causing serious bodily injury, receiving a 20-year sentence. The case highlights the complexities of legal proceedings and the determination of grieving families seeking justice.
