oh, gosh... Syracuse police conducting searches for additional victims SYRACUSE, New York (CNN) -- Two days after a convicted sex offender confessed to killing two women in his apartment building, police said Thursday they were carrying out additional searches and believed they could find more bodies. Nicholas Lee Wiley, 41, who had been released from prison in January, was arraigned Wednesday on two counts of second-degree murder after the bodies of two women were found in his apartment building. The Syracuse Police Department said Wiley "indicated that there are other victims." Monday, police found the body of a 31-year-old woman in her apartment in the same building in which Wiley lives, according to Sgt. Thomas Connellan. While crime scene investigators searched the building Tuesday, the body of a 22-year-old woman was found in the building's trash bin. Both women had been stabbed multiple times and their throats were slashed. Lamar Kearse, the building's landlord, said Wiley had lived there a few months. "He's quiet, stayed to [himself]," Kearse said. "He was looking for odd work. I let him cut the grass or stuff like that. I never assumed he was the way he is." Connellan told CNN that Wiley was taken in for questioning Monday after investigators learned that the Level 3 sex offender lived in the same building. A Level 3 offender is considered by law enforcement to be at the highest risk to commit the crime again. Wiley had been released from prison in late January after serving a sentence for sexually assaulting a teenage girl. Wiley confessed Tuesday to killing both women, Connellan said. "We are investigating the possibility of more, unreported victims," the sergeant said. The current charges may be upgraded to first-degree murder if autopsies on the victims show evidence of torture, or if more victims are found. A first-degree murder charge would make Wiley eligible for the death penalty. His record also includes convictions and prison sentences for beating and robbing a woman in her 60s in 1983 and stabbing a woman in the chest in 1979. After a 1991 release, Wiley beat and sexually assaulted a 16-year-old girl on his 29th birthday, according to Connellan. In March 1992, he was convicted of first-degree sodomy and sentenced to 12 to 25 years behind bars, the maximum penalty. Connellan said this conviction was overturned because of a legal technicality, and Wiley was convicted on a lesser charge and sentenced to 6 to 12 years in prison. After his January release, Wiley was required to report every 90 days to police, which he did, Connellan said.
