Authorities say a man who fatally stabbed and beat his girlfriend inside a Camden home, and then tried to make it look like she had killed herself, has been charged with her murder.

According to the Camden County Prosecutor’s Office, Edwin Zavaleta, 28, of Camden, also faces tampering with evidence charges in the death of Tonia Yamileth, 25.

Zavaleta remains jailed pending a detention hearing, and it wasn’t known Wednesday if he had retained an attorney.

Yamileth was found Monday morning in an upstairs bedroom at her home. Authorities say she had a stab wound and blunt force trauma to her neck.

A motive hasn't been disclosed.
