LAKE COUNTY, Calif. – A Kelseyville man has been charged with murder after his wife died from injuries she suffered in a brutal assault last week.

The Lake County Sheriff’s Office said Travis Ryan Bonson, 45, has been charged with first-degree murder for the death of 44-year-old Ayano Bonson.

Travis Bonson was arraigned for the homicide charge before Judge J. David Markham on Wednesday afternoon.

At 8 a.m. Jan. 16, the Lake County Sheriff’s Office Dispatch responded to a residence in the 5900 block of Single Spring Drive after receiving a call from Travis Bonson.

He told authorities he had physically assaulted a female adult, who the sheriff’s office confirmed on Thursday was Ayano Bonson.

Sheriff’s deputies responded to the residence and located Ayano Bonson, who was in critical condition. She was transported to an out of county hospital for medical treatment.

The sheriff’s office said Ayano Bonson died of her injuries on Tuesday.

The Lake County District Attorney’s Office charged Travis Bonson with first-degree murder on Wednesday, the same day that he was arraigned, according to court records.

The sheriff’s office said Travis Bonson remains in custody and is being held without bail.

Travis Bonson’s criminal record includes a 2005 conviction for misdemeanor assault and battery that occurred in August 2004.

In 2012, he was convicted of a felony, committing lewd or lascivious acts on a child under age 14, and sentenced to three years in state prison. State records show he was actually released from prison in 2014. 

In 2015 he was sentenced to six months in county jail after his felony probation was revoked.

Bonson is listed as a registered sex offender on the Megan’s Law website. 

The sheriff’s office said the investigation into Ayano Bonson’s murder is ongoing. 

Anyone who believes they may have information related to this case is asked to contact the Lake County Sheriff’s Office Major Crimes Unit at 707-262-4088 or Sgt. Jeff Mora at 707-262-4224.
