[Richard Evonitz], 38, said he had killed someone and that he had committed "more crimes than he can remember," Richland County, S.C., Sheriff Leon Lott said today. Evonitz mentioned only scant details about that killing, but it was enough to determine that he was not referring to the slayings of three Spotsylvania County, Va., girls, Lott said.

Lott declined to say what details have led him to believe that Evonitz was not referring to the [Kati Lisk] slayings when he talked to his sister. The conversation took place before he killed himself after a police chase in Florida. But inside Evonitz's apartment, detectives found a Fredericksburg, Va., newspaper from the day after the Lisk abductions and notes about the girls, along with directions to a location near their home. They have not said whether they found similar evidence about the [Sofia Silva] killing, but they have previously said that scientific evidence links the two cases.

Evonitz took the girl to his apartment, where they were alone because his wife and mother were vacationing at Walt Disney World, and carried the container inside. Lexington County Sheriff James R. Metts said Evonitz tied the girl up and raped her. He forced her to watch the evening news to see if there was a report of her kidnapping.
