A Pacifica man convicted of stabbing his ex-girlfriend's new boyfriend in the head with an ice pick has been sentenced to more than nine years in prison, a prosecutor said.
Arthur John Armstrong, 39, got eight years behind bars for the ice pick attack, which left the victim with permanent disabilities, and 16 months for a separate incident in which he opened fire while being pursued by a Pacifica police officer, San Mateo County District Attorney Steve Wagstaffe said.
Judge Clifford Cretan handed down the sentence Thursday.
The stabbing happened Nov. 15, 2010, when Armstrong, who was with his new girlfriend, spotted an ex-girlfriend and her boyfriend near the Pacifica pier. The men exchanged stares and words before Armstrong allegedly tossed a lit firecracker at the victim. At that point the victim, whose name was not immediately available, confronted Armstrong and was stabbed.
Wagstaffe said the pick went through the victim's skull and into his brain, leaving him with permanent damage to his motor functions. Armstrong was arrested a short time later and denied responsibility for the stabbing.
While Armstrong was out on bail in connection with the ice pick attack, he fired two gunshots as a Pacifica police officer chased him through backyards, Wagstaffe said. The pursuit began when an officer spotted Armstrong speeding in a car March 23. He then allegedly crashed the car and took off on foot, with the officer right behind
Police found the gun two days later and linked it to Armstrong, authorities said.
Armstrong pleaded no contest to assault and reckless discharge of a firearm, both felonies, on April 17 as part of a plea bargain.
