An arrest in Pennsylvania could help solve a murder in Orleans county that's been a mystery for three years. Pennsylvania State Police arrested Steven P. Rebert, 45, on Friday in connection with the murders of a man and woman earlier this year in Jefferson County, PA. In Western New York the Orleans County Sheriff's Office is calling Rebert a "person of interest" in the February 2007 murder of Kevin smith. His body was found inside his home in the town of Shelby. Autopsy results showed that Smith died from multiple gun shot injuries. The investigation into that case is on-going.
