William Spengler Used Bushmaster Rifle in Fatal Shooting of Webster Firefighters, Left Chilling Suicide Note

WEBSTER FIREFIGHTER SHOOTING:  Dawn Nguyen, of Rochester, was arrested Friday and charged in connection with ex-con William Spengler’s Christmas Eve ambush slaying of Webster NY firefighters Tomasz Kaczowka and Lt. Mike Chiapperini, and wounding two others.

Dawn Nguyen faces a state charge of filing a falsified business record, State Police Senior Investigator James Sewell said. Nguyen also faces a federal charge; a news conference with the U.S. attorney in western New York was scheduled for 4 p.m. Friday.

Sewell said the state charge is connected to the purchase of an AR-15 semiautomatic rifle and a 12-gauge shotgun that William Spengler had with him Monday when firefighters Michael Chiapperini and Tomasz Kaczowka were gunned down. Three other people were wounded before the 62-year-old Spengler killed himself. He also had a .38-caliber revolver, but Nguyen is not connected to that gun, Sewell said.

The .223-caliber Bushmaster rifle, which had a combat-style flash suppressor, is similar to the one used by the gunman who massacred 20 children and six women in a Newtown, Conn., elementary school earlier this month. Source
