Buehler was last seen near her Houston, Texas residence on September 8, 1990, two days before her nineteenth birthday. Her car had a flat tire and she parked the vehicle near the corner of Westheimer and Beltway 8. Investigators believe that Buehler then attempted to walk the half mile back to her residence, but she never arrived. Buehler has not been seen again. Foul play is suspected in her disappearance. Buehler's nickname is Shelly and she may go by her middle name, Michele (also spelled "Michelle"). She has four tattoos as follows: the word "Taxi" with a red and black heart, a musical note and a zigzag on her upper left arm; the phrase "Wicked Innocence" with a long-haired skull on her right shoulder; a cigarette-smoking skull on her left breast; and a red rose with a spiderweb on the back of her right shoulder.
