Catherine Lynne Sjoberg was last seen on June 5th, 1974 leaving Concord Center House from the Oconomowoc High School post-prom party during the early morning hours.
The prom was held at the Jefferson County Concord House dance hall on Interstate 94 interchange in Concord, Wisconsin.
According to a friend, Catherine stepped outside the Concord House around 3:00am for a breath of fresh air and never returned.
Catherine is described as a white female with long and straight brown hair, parted in the middle in 1970’s style.
She has green eyes, freckles, high cheekbones and both of her ears are pierced.
When she was last seen, Catherine was wearing a long formal blue prom dress with white flowers and a corsage. She had on high heeled shoes and was wearing a gold chain and a gold pin.
Because she was supposed to spend the night at a friend’s house, her mother didn’t realize she was missing until the next day. Her mother does not believe that Catherine ran away.
She is 5’5”, 115-125 pounds, and was 17 years old when she went missing.
Here are a few age progression photos that have been done over the year of Catherine. She would be 64 years old today.
