A 25-year-old woman is scheduled to be sentenced for lying on firearm transaction documents when she bought the guns used by a man to kill two Rochester-area volunteer firefighters and wound two others on Christmas Eve 2012.
Dawn Nguyen of the town of Greece faces a maximum of 1 1/3 to four years in state prison when she's sentenced Monday in Rochester.
She was convicted last month of falsifying business records when she filled out forms to buy a rifle and shotgun in 2010 for her neighbor William Spengler Jr.
Spengler was prohibited from owning weapons because of his felony record for killing his grandmother.
He set fire to his lakeside home in Webster on Dec. 24, 2012 and used the guns to shoot four firefighters before committing suicide.
