VIDEO: Drone footage shows the aftermath of the massive fire that ravaged the former Strathmore Paper complex and destroyed Mill Number Two. The footage was taken Saturday by Samuel Mazzaferro, the owner and operator of West Branch Aerial Photography located in Chester. Mazzaferro made sure to follow all rules and regulations and avoided any interference as firefighters continued to work the scene. The cause of the fire inside the vacant mill in Russell is considered suspicious by investigators, who are now offering a reward for information that helps identify those who are responsible. The fire was reported around 8:30 p.m. Friday and burned for more than 12 hours. More than 125 firefighters responded to the scene on 34 Valley View Ave.
