Real Life 'Dexter': Former Crime Scene Investigator Accused of Committing Murder

A former crime scene investigator is playing a central role in a murder inquiry, but this time as the suspected killer. Ashley McArthur once helped solve crimes for the Escambia County Sheriff's Office, where she's now accused of killing a former police officer whose body was discovered in a cement-covered grave last week. The victim, 33-year-old Taylor Wright, was first reported missing Sept. 8. Investigators initially said no foul play was suspected in her disappearance.
