Rochester N.Y.-  A clerk at the Gander Mountain store has testified he recalled Dawn Nguyen buying the firearms that were eventually used by William Spengler to kill Spengler's sister and two Webster firefighters on Christmas Eve 2012.


Antonio Garcia told a jury Monday that Spengler was with Nguyen when she bought the guns.


She's accused of knowingly buying guns for a felon. She had claimed the weapons were stolen from her.
