Clara Maria Grunst, 21, disappeared after leaving Joplin, Missouri, for Milwaukee on October 9, 1984. Last known movements place her at Interstate 44 and Highway 43 in Joplin, where she reportedly got into a truck driven by a man from Milwaukee. Her final contact was a payphone call from Pittsburg, Kansas, at about 11:40 a.m.; she was never heard from again.

Clara was distinctive: blonde hair, blue eyes, large light-beige framed eyeglasses, pierced ears, scoliosis, a red birthmark on her navel, and a tattoo reading Jeff on her left forearm. She wore a white shirt with a floral waistband, reddish-brown pants, blue athletic shoes, a Timex watch with a blue band and a silver ring. Family said she carried a large sum of cash and a new suede coat given by her brother. Known on CB as Blondie, Blue Eyes, and Missouri Sunshine, she frequently hitchhiked.

Investigators questioned the truck driver she was last seen with; reports say his statements were inconsistent but produced insufficient evidence to charge him. The family later held a memorial in 2011, and Clara’s mother died in 2019 without learning what happened. Does anyone have information about Clara’s movements after the Pittsburg call or recall the truck or driver that day?
