CAMDEN, N.J. (AP) — A man who fatally stabbed and beat his girlfriend inside a southern New Jersey home and then tried to make it look like she had killed herself has been charged with her murder, authorities said Wednesday.

Edwin Zavaleta, 28, of Camden, also faces tampering with evidence charges in the death of Tonia Yamileth, according to the Camden County Prosecutor’s Office. Zavaleta remains jailed pending a detention hearing, and it wasn’t known Wednesday if he has retained an attorney.
