Jelovcic was a violinist with the Detroit, Michigan Orchestra in 1996. She married that same year; her husband was killed in a traffic accident six months after their wedding. Jelovcic returned to her family's home in Gary, Indiana shortly after his death and managed the night shift at her mother's tavern.

Jelovcic met Randy Mark Yager upon her return to Indiana. Photos and Yager's 1997 vital statistics are posted below this case summary. Yager was the regional president of the Outlaws Motorcycle Club in Chicago, Illinois in 1997. Jelovcic was not aware of his criminal history and did not know Yager and other Outlaws members were under investigation for several felony charges. They began dating shortly after they met and Jelovcic's loved ones said they noticed a change in her behavior. Jelovcic and Yager traveled to Las Vegas, Nevada for a vacation three months into their relationship. Jelovcic's family said that she was not aware of the fact that 17 Outlaws' members were indicted during that time on various charges including racketeering, bombings and six murders in the midwest. Authorities traced Yager to Nevada, but he and Jelovcic fled the area before he could be apprehended.

Jelovcic returned to Indiana alone two weeks afterwards. Her family stated that she seemed to be more devoted to Yager by that time. Jelovcic disappeared three months later in 1997 and has never been heard from again. Investigators believe that she may be accompanying Yager. Jelovcic is not wanted for any crime; she is considered an endangered missing person. Authorities are not sure if Jelovcic left of her own accord or if foul play was involved in her disappearance. Her family is concerned for her safety.

The United States Marshals Service in Wisconsin issued a warrant for Yager's arrest on federal racketeering (RICO) charges and weapons charges in June 1997. He is considered armed and dangerous.
