Wendy Lorraine Camp was 23 when she disappeared in May 1992 after a planned visit in Shamrock, Oklahoma to see her young son. She was last reported seen with her six-year-old daughter Cynthia Britto and her sister-in-law Lisa Kregear, 23, after an argument ended the visit. Beverly Noe, the boy’s paternal grandmother, told investigators she had dropped the three off at a Walmart in Chandler; that is the last known sighting.

The case remained cold for decades until a 2013 tip led investigators to a rural property near Jennings, Oklahoma. Buried eight feet below ground in a hole intended for a septic tank, skeletal remains matching the three missing females were recovered; clothing found with the remains matched descriptions of what they had been wearing the day they vanished. Grover Prewitt, the landowner and Beverly Noe’s brother, was arrested in connection with concealing the deaths and later said he suspected the women had been murdered and disposed of on his property.

Authorities later focused on Beverly Noe and alleged the motive was to prevent Wendy from gaining custody of her son. No contest pleas were entered in connection with the killings. Is there anyone who knew Wendy, Cynthia, or Lisa or who has information about that May 1992 visit?
