The house where the brothers were killed is in Bensonville. I've passed by it many times. The house was owned at the time by a relative of Lee Magnafichi. I believe it was his brother in laws house. It's near the intersection of Irving Park Road and Route 83. The house is on Bryn Mawr. I have the exact address written down somewhere. Nick Calabrese couldn't remember the exact house because it was so long ago. Apparently the feds know but didn't want to sway Nick's testimony by telling him so they hoped he would pick it out without the help of the feds. I've heard the feds at some point did search the basement for blood samples but found nothing.
