ROCHESTER, N.Y. (WROC) — Dawn Nguyen, the woman who bought the gun used in the Christmas Eve ambush that killed two local firefighters, is now free after being released from a halfway house in Pittsburgh on June 4.

Nguyen, 32, had been sentenced to 8 years in prison.

Last last year, she was moved out of Alderson minimum security federal prison camp and transported to a residential reentry management (RRM) field office.

William Spengler, a convicted felon, ambushed West Webster firefighters when they arrived on scene of a fire, killing Tomasz Kaczowka and Michael Chiapperini and injuring Ted Scardino and Joe Hofstetter on the morning of Christmas Eve 2012. Nguyen had purchased the gun Spengler used two years prior; she said he asked for the firearm for hunting purposes.

Spengler took his own life that day.

Over the last year, Nguyen tried to convince a judge to release her early citing health concerns during the COVID-19 pandemic, but the judge declined those requests.
