More than two years after the murder of a Petaluma woman in her home, the Sonoma County Superior Court will hear opening arguments today in the case against Kenneth Mullennix, who is charged with killing his wife after learning that she was having an affair.
Following the January 9, 2010 murder, Mullennix, a contractor, called 911 and admitted killing his wife, claiming self-defense.
He has been charged with first-degree murder and possession of an assault weapon and faces 50 years in prison.
During a preliminary hearing last year, Buapha Mullennix's boyfriend testified that she feared for her life. Friends and coworkers had said Buapha Mullennix was a victim of domestic violence, but was afraid to seek help because she was an immigrant from Thailand and may have not know how to seek help.
