When a young Spokane, Washington woman goes missing, it’s not reported until more than a year later. Investigators unravel the story of a vanished woman whose adopted family called her their real-life “Cinderella” in this episode of Last Seen Alive.

When investigators eventually searched the home, they discovered that the DVR containing security footage was nowhere to be found.
While in her early 20s, Courtney gave birth to a son, who was the light of her life. After police began investigating Courtney’s disappearance, her adopted mother and brother fled to a different state with her son, who they hid from his father until investigators located them. Image source: family photo.

UNSOLVED HOMICIDE: DIANA VICARI

When a young Tucson, Arizona woman goes missing, her partial remains are discovered in a dumpster just days later. Potential suspects and unanswered questions haunt a case gone cold in this episode of Last Seen Alive.

Diana Vicari was 19-years-old when she was murdered in Tucson, Arizona in October of 1992. She was a hard-working college student who held down two jobs in addition to her studies. She loved animals and aspired to become a marine biologist. Image source: family photo.
After her death, Diana’s vehicle was located in the 1200 Block of W La Osa Dr (Tucson), a residential area. A large house party had occurred in the area on the night of her death, and it’s believed she may have been in attendance. Image source: Google Maps.
Gregory Hatton (pictured) is one of several known criminals whose name has arisen in court documents in connection with Diana’s case. Although Hatton has never been charged with any crime in relation to Diana’s death, he is currently incarcerated for other serious, violent crimes. Image source: Arizona Department of Corrections.
Diana’s partial remains were found in a dumpster in an alley just north of downtown Tucson (approximate location denoted by red marker at bottom of map). Her vehicle was found several miles north, in the 1200 Block of W La Osa Dr (approximate location denoted by red marker at top of the map). It’s believed that her partial remains were transported to the dumpster from elsewhere via vehicle, as a tracking canine was unable to locate Diana’s scent outside of the dumpster. Image source: Google Maps.
Diana is pictured on the cover of Tucson Weekly along with a mug shot of Lemuel Prion, the criminal who was convicted of her murder, but later exonerated. There is no known physical or conclusive evidence linking Prion to her death. Image source: Tucson Weekly.
