Christine Ruth ’Chris’ Thornton was a 28-year-old white female who left San Antonio, Texas in 1977 while newly pregnant and traveling with a boyfriend toward Montana. The couple split in Biloxi, Mississippi, and Christine continued north alone. On April 6, 1982 a rancher found skeletal remains northeast of Granger in Sweetwater County, Wyoming. The woman was long known as Granger Greta; investigators determined she had been six months pregnant and was a homicide victim.

Photographs seized from a convicted killer in 2010 included an image of a young woman on a motorcycle in terrain like the Granger site. In 2013 family members identified her from the photo, and in July 2015 DNA from Christine’s siblings matched tissue preserved from the scene, confirming her identity as Christine Ruth Thornton. Sweetwater County prosecutors later charged Rodney James Alcala in connection with her killing, alleging she had been strangled after being driven into the Wyoming high desert during the summer of 1977.

Did anyone who knew Christine in San Antonio or along her 1977 route ever see her after she left the city?
