A man was sentenced to 11 years in prison for killing a woman whose body was found sealed in a Lomita apartment wall in 2015, officials announced Tuesday.

Raven Joy Campbell is shown in a photo released by the Los Angeles County Sheriff’s Department when she disappeared in August 2009.

Randolph E. Garbutt, 47, of Los Angeles, pleaded guilty last month to voluntary manslaughter in connection with the death his roommate Raven Campbell.

The victim’s body was excavated from behind a wall of a home in the 26800 block of Western Avenue on July 2, 2015. Campbell had been missing since 2009, when she was 31, and officials determined she died of blunt force trauma to the head.

The criminal complaint against Garbutt indicated he used a hammer to kill Campbell.

A detective received a tip that her remains were in the wall of an apartment in a public housing complex where she had lived with her friend, the friend’s boyfriend, and Garbutt, officials said at the time.

It is unclear how the body ended up behind a patched-up hole in the wall of a closet.

Garbutt was arrested seven months after the body was discovered.

The case was investigated by the Los Angeles County Sheriff’s Department.
