A sex offender, sentenced to death for killing a 12-year-old Omaha girl, will have his appeal heard Tuesday by the Nebraska Supreme Court.
Roy Ellis is under a Nebraska death sentence for sexually assaulting and killing Amber Harris in November of 2005. The girl's body was found buried in a remote Omaha park in the spring of 2006.
Ellis argues in his appeal that his jury was tainted by testimony about previous sexual assaults he had committed.
During his murder trial for killing Harris, two women were allowed to testify that Ellis repeatedly raped them when they were ages 14 and 12, respectively, and that he fathered a child with each of them.
Ellis was convicted of first-degree murder for killing Amber Harris. Prosecutors have said Ellis killed the girl during a sexual assault.
State attorneys say there were no witnesses to Amber's death, so testimony of Ellis' prior assaults was needed to show similarities to Amber's killing.
