Thread: Where is Ryan Lanza? Where is the father, Peter Lanza? No interviews? No paparazzi hounding them 24/7...???

Also, it was reported today that supposedly, the father Peter Lanza claimed Adam Lanza's body (his son.) But, the same report also states that Dr. H. Wayne Carver, CT State M.E., will look for "genetic" clues to what made Adam Lanza kill 26 strangers including 20 children, his mother, and then himself, or at least he is suspected of doing so.

How can both of those be true? How does the UConn Genetics Lab conduct experiments without Adam Lanza's body?
How did the father "claim" his son's body? Did he just get "the leftovers" the UConn Genetics Lab & Dr. Carver didn't need???
