Considering nobody is ruled out, it is a possibility. He's the only one who heard the scream. His mom didn't hear it. Clint didn't hear it. Wish we knew more about the neighbour. We don't even know his age. I thought living with mom would put him in the 20+ but if he owns his own company (do we know that for a fact - I don't recall) then he must be in his 30's or 40's?:waitasec:
His hame is JB right? There is a construction company with his full name, one employee (himself), home construction. Haven't been able to find anything definitive about his age but had read around 40.
