They communicated this to the officers and tried to save the boy. However, Balcerzak and his partner returned Konerak to Dahmer's apartment, against the women's protests. The officers noticed a strange smell in Dahmer's apartment, which was the decaying corpse of a previous victim in the bedroom, but made no attempt to investigate. Later that evening Dahmer sexually abused, killed, and dismembered the boy.
Balcerzak's and Gabrish's positions and roles within the Milwaukee Police Department were terminated[2] after their actions were widely publicized, including an audiotape of the officers making homophobic statements to their dispatcher and cracking jokes about having reunited the "lovers". The officers had never checked the boy's ID or verified his identity. The officers did not check Dahmer's identification; had they done so, they would have discovered that Dahmer was a sex offender previously convicted for molesting Sinthasomphone's older brother.
