Accelerants Found at Site of Berkshire County Murder-Suicide

The Berkshire County District Attorney's office released additional information Monday night, regarding the murder-suicide of a family of five found dead after a house fire on Home Road in Sheffield last Wednesday.

The DA's office said investigators determined that Luke Karpinski, the suspected assailant in the tragic incident, killed his wife, Justine Wilbur, and their three children, and intentionally set fire to the home, before taking his own life.

Investigators also found evidence of accelerants in different parts of the home, including two, 20 pound propane tanks on the upper floor.

The body of Wilbur was found on the first floor of the home.

Wilbur was a senior associate for Albany law firm Hoffman Warnick.

The District Attorney says that she sustained a traumatic injury before the fire was started.
