Added police Lt. John Slusarz: “He is a recognized expert in the field of forensics, he and his team. He’s very meticulous in locating, collecting and identifying trace evidence. It could be fibers, hairs or DNA from the inside of a hat.”

Corticelli was an investigator in the Andrew Kissel homicide investigation in 2006, resulting in two guilty pleas and jail sentences.

Da Silva is being held in custody on a federal charge of kidnapping resulting in murder, in connection with Reyes’ death. A 24-year-old bookstore worker, Reyes once Da Silva a year ago.
