In WA state what happens if the alleged victim fails to appear for domestic violence court hearing

In criminal cases, including domestic violence allegations, the prosecutor must prove the case beyond a reasonable doubt to sustain a conviction. If the victim is the only person who says there was abuse and he or she does not come to court to testify, it is likely that the case against the defendant will be dismissed. However, there are sometimes alternative ways to prove up a case. For instance, if a third party witness saw the battery or abuse, the state might be able to call that witness to prove the case without the presence of the victim. Also, if the defendant confessed to the abuse, the prosecutor might use that custodial statement as a "statement against penal interest" to prove the crime without the victim.
