Detectives investigating the disappearance of 84-year-old Nancy Guthrie allegedly overlooked dried blood on the front porch of her Arizona home in the crucial hours after she vanished, according to a bombshell report. Guthrie disappeared from her home outside Tucson on February 1, and no arrests have been made. Sources within the Pima County Sheriff's Office told The Wall Street Journal that homicide detectives allegedly "gave little regard" to the blood evidence, potentially hindering the investigation. #NancyGuthrie #savannahGuthrie #TheCrimeDesk #TrueCrime
