California authorities say they have found what they believe to be the remains of a missing mother two months after she disappeared. CBS Sacramento reported that the discovery of El Dorado County woman Heather Gumina prompted a homicide investigation by the county sheriff's office, which led to the arrest of her husband.

Sheriff office officials say her 44-year-old husband Anthony Gumina was arrested Friday on suspicion of felony domestic violence and first degree murder. Authorities served him with a no bail warrant for domestic violence and a search warrant.

Police say the human remains were discovered during the search in the Pleasant Valley area east of Sacramento. Gumina and her car were reported missing in July.

Tuesday's court appearance gave a glimpse into why prosecutors believe Gumina killed his wife.

A new criminal complaint states he killed her because "Heather Gumina was a witness to a crime and was intentionally killed to prevent her from testifying in a criminal proceeding."

That may be referring to a January case when Gumina was charged with headbutting Gumina Waters and tackling her while she held her 4-year-old son. He was also accused of kicking in doors and forcibly removing phones from his wife in order to prevent her from dialing 911, according to court documents.
