Human remains removed from a hollow wall of an apartment in California on Thursday are believed to belong to a woman who vanished in 2009. An anonymous tip led detectives to the Harbor Hills Housing Project in Lomita where Raven Campbell, 32 at the time, once lived.

Although it is considered too soon for authorities to determine the cause of death or identify the body as Campbell’s, one major piece of evidence led her sister Malaikah Manasseh to believe there was foul play involved.

#UPDATE: Per #LASD, the possible human remains were found in the 26800 block of Western Ave. http://t.co/bXR7JOBZFv pic.twitter.com/VA8bhCQcWA — CBS Los Angeles (@CBSLA) July 2, 2015

“She had a ti …and that was not leaving her purse,” which she always wore strapped against her chest Manasseh told the Los Angeles Times.

Someone had reportedly called Manasseh two weeks ago, telling her they believed her sister’s body was in a “downstairs apartment in the wall of the closet behind the stairs.” The Times notes that neighbors had complained of a bad odor near the unit where the body was found.
