Boomer visited Uncle Mike's Bar (now called Nobody's Business) in the 4900 block of Metropolitan Avenue in Kansas City, Kansas, near her own residence, on February 23, 1999. She originally went there with a roommate, Carolyn Marshall. Marshall stated while they were in the bar, a male stranger walked up to Boomer and threw her off the barstool, for no apparent reason, and without speaking to her. Boomer got up and insisted she was all right, and her attacker was forced to leave the establishment. Marshall left after finishing her drink, She asked the bartender to keep an eye on Boomer, whom she planned to pick up later. When Marshall called the bar later that day, she was told Boomer had already left with two men. Boomer was carrying a purse with $80 cash at the time of her disappearance. She has never been heard from again. Marshall reported her missing five days later.

Witnesses at the establishment told authorities that she was involved in an altercation with another patron during the evening. The individual is believed to be a career criminal with a history of violent behavior towards women. He allegedly knocked her to the ground and beat her, causing her to lose consciousness. She has never been heard from again. Authorities believe she may have been murdered in the bar and her body hidden in another location.

In October 1999, two local men, William "Geno" Spradlin and Robert "Butch" Horn, were charged with second-degree murder in Boomer's case. Both suspects have extensive criminal histories and have served time in prison. The murder charges were later dismissed because over a dozen witnesses to the alleged crime refused to testify against the defendants. Authorities believe that several people have information related to Boomer's case, but the individuals have not come forward. Foul play is suspected in Boomer's disappearance due to the circumstances involved.

Boomer resided in the 1700 block of south 49th Street in Kansas City in 1999. She was going through a divorce at the time of her disappearance, and planned to move back in with her parents. She has six siblings. She had dropped out of Turner High School, but was studying for her GED certificate, and dreamed of becoming a florist. Boomer left behind a young son, who was raised by his grandparents after her disappearance. Her case remains unsolved.
