No one saw who killed Bill Chamberlain, but 29-year-old Joseph Vandenburgh's blood was at the crime scene and his DNA was on the murder weapon. Now the jury has to decide if that's enough to convict him of murder.
In December 2015, the 56-year-old director of operations in Troy walked his dog through his Wynantskill neighborhood. The dog came home, but Chamberlain didn't. His wife found him outside with more than a dozen stab wounds. Vandenburgh's DNA was found on the knife police say killed Chamberlain. While he lives in the area, it's still unknown if the two men knew each other.
The defense argued that's why Vandenburgh is innocent.
But in addition to DNA on the murder weapon, Vandenburgh himself had blood on his sweatshirt and sneakers, and an injury on his hand. His own blood was found all over the crime scene. The defense says he was either helping Chamberlain or defending himself, yet the defendant never told anyone what happened that night or called for help. Shortly after the murder, authorities say he painted words on his bedroom wall and stabbed his bloody sweatshirt next to them.
The jury began deliberating around 2:30 Thursday afternoon. After a couple of notes, the jury was sent home for the day just before 5 p.m. Jurors will begin Friday by hearing a definition of criminal possession of a weapon, one of the counts Vandenburgh is facing -- in the third degree -- along with one count of second degree murder.
