SUNBURY - A Port Trevorton man charged with homicide by vehicle pleaded guilty Monday in the deaths of a man and his young son on Veterans Memorial Bridge July 2012.

The Daily Item reported Brian Glass, 27, was in court for jury selection when he entered his plea on several felony charges and driving under the influence of a controlled substance.

Chemical testing performed shortly after the accident showed Glass was drunk and high when he drove an unregistered Jeep into a vehicle driven by Kirk Mahaffey, of Northumberland; Mahaffey's three-year-old son, Mason, was a passenger. Several experts said Glass was mentally ill and suffered from post-traumatic stress disorder after several years of service in the military, the newspaper said.

Glass' brother, Cody, who was interviewed November 2012, said he and Brian Glass had snorted Vicodin and drank alcohol several hours before Brian drove a Jeep Liberty into the path of Mahaffey's vehicle, causing a head-on collision, the newspaper reported.

The brothers had also smoked marjiuana and drank vodka shortly before the accident.

Blood tests on Brian Glass were positive for marijuana and morphine; his blood-alcohol content was .14, the newspaper reported.

Glass will be evaluated again. Sentencing is scheduled before Northumberland County Judge Charles Saylor June 26.
