Feiner resided in Oakdale, Minnesota with her brother. She received a ride to a friend's home in St. Paul, Minnesota on May 8, 1992. Feiner stopped at Chuck's Bar on Payne Avenue in St. Paul during the evening hours. Witnesses told authorities that she was danced with three men at the establishment early in the morning on May 9. She was last seen speaking to one of the men outside of the building at 1:00 a.m. Feiner never returned to her residence and has not been heard from again.

Feiner's brother reported her as a missing person on May 12. Her family members said that it is uncharacteristic of her to leave without warning. She and her former husband divorced earlier in 1992 and shared custody of their two children.

Authorities identified the three men who had contact with Feiner at Chuck's Bar shortly she vanished. The men were described as construction workers and all of them denied involvement in her case. Two of the individuals provided alibis for their whereabouts after departing from the bar; the third man was unable to account for his time afterwards.

Authorities believe that foul play was involved in Feiner's disappearance and are investigating her case as a probable homicide. No arrests have been made in connection with her case, which remains unsolved.
