A man who had been living with his mother in Santa Rosa while he battled methamphetamine addiction has been sentenced to life in prison for stabbing her to death, prosecutors said Monday.
Christopher Anthony Lavis, 43, pleaded guilty in October to first-degree murder and two weapon enhancements in the Sept. 27, 2008, slaying of his mother, Constance Elizabeth LaSalle.
Lavis must serve at least 26 years behind bars before he is eligible for parole, Sonoma County prosecutors said.
LaSalle, 63, was found dead in her apartment on the 300 block of Stony Point Road. She had been stabbed 45 times in her head, neck, chest, back and arms with two knives, authorities said.
Lavis was originally charged with the special circumstance of torture, which carries a sentence of life in prison without the possibility of parole. But prosecutors agreed to drop the torture accusation as part of a plea deal with Lavis, who agreed to give up all his rights to appeal.
