Disappearance of Sylvia Linda Klayh

On August 13, 1967, 14-year-old Sylvia Klayh and her family were at their family cabin in Brereton Lake, Manitoba, Canada. Around 11 a.m. Sylvia and her father had an argument. She left the cabin without a word. When she didn't return for lunch her father reported her missing.

There was a ground search of the surrounding area of the cabin, but there was no trace of her. As she did leave the cabin on her own accord she was first considered a runaway, but since there has been such a long time without contact it's possible she met foul play.

Sylvia is a white female and was 14 at the time she disappeared. She may also be using the last name Ciprianovich. She was  5'6" and 119 lbs at the time. She has long brown hair and brown eyes.
