A 39-year-old Carson City man has pleaded guilty to assault with a deadly weapon after firing multiple shots during a standoff with a SWAT team at his grandmother’s home. Christopher Conti also pleaded guilty to a misdemeanor charge of possession of a firearm while intoxicated on Tuesday and was sentenced to 30 days jail on that count. District Attorney Jason Woodbury said Conti will be sentenced Feb. 11 on the more serious felony count. Sheriff’s deputies say Conti was intoxicated and suicidal when he fired 10 rounds from a .45-caliber revolve inside the house of his 73-year-old grandmother on Dec. 4.
