Holik was last seen have a drink with some friends at a restaurant near the Taos Plaza in Taos, New Mexico on June 23, 1995. She sold jewelry and handmade pottery at a local gallery. After she didn't show up for work on June 27, her employer contacted the police. When Holik's friends went to her home, they found the door open and her vehicle parked in the driveway. Her purse, identification and other belongings were inside her apartment, which appeared undisturbed. She has never been heard from again.

A few days after her disappearance, a pair of Holik's shoes was found in a vacant apartment in her building. She had access to the apartment in order to turn the outside lights on and off. There was no other sign of her at the scene.

Holik was born and raised in Germany, where her family still lives, and moved to the United States at age 28. At the time of her disappearance, one of her friends was traveling from Germany to New Mexico and Holik was expecting the friend to visit her. She is described as a quiet, shy and very organized individual, and it's uncharacteristic of her to leave without warning. Foul play is suspected in her disappearance, which remains unsolved.
