Former Prince William County crime scene investigator Andrea Feldman testified Monday that she observed reddish-brown stains and black hair-like strands inside a Ryobi electric saw Naresh Bhatt gave to a landscaper shortly after his wife disappeared, WTOP reported.
She said she believed the stains were blood. The saw was purchased at a Home Depot less than two months before the disappearance, according to the report. Defense attorneys challenged aspects of the investigation and noted some test results were negative.
