and other complex matters in state and federal courts.


Ms. Muth has represented numerous individuals faced with sex and domestic violence charges. Her representative successes include:

Not guilty verdict for individual charged with Rape in the Second Degree. Client's DNA had been located as evidence. Jury acquitted in forty minutes.

Dismissal of multiple counts of first degree child molestation and child rape on grounds that individual was incompetent to stand trial, after two years of litigation and extensive expert consultation.

Agreed sentence of six months, one count, felony violation of a court order-domestic violence, for individual charged with calling his wife continuously from the King County Jail. Defense provided with 50 CD-ROMs of jail phone call recordings. Presented extensive mitigation package to state which convinced state to recommend exceptional sentence downward instead of seeking convictions to place client in prison for 60 months.

Special Sex Offender Sentencing Alternative for client convicted of molesting younger brothers over a four-year period, to be completed out of state, in Utah.

Hung jury in sexually violent predator civil commitment trial in Pierce County.

Dismissal of multiple counts of first degree child molestation against an Ethiopian immigrant who had received asylum to live in the United States.

Dismissal of charges of first degree child molestation against a female client. Investigation revealed that the accuser had extensive mental health issues which impacted his credibility.

Successfully litigated a challenge to the sexual assault advocate privilege statute. First degree child molestation charges reduced to third-degree assault and communicating with a minor for immoral purposes. Original charges carried a penalty of 51-68 months in prison; client released from jail after serving eight months.

Reduction of first-degree child molestation charges to misdemeanor fourth-degree assault charges. Client was mother of child. Six months of expert consultation and investigation revealed that police had incorrectly reported that client failed a polygraph, daughter was improperly influenced by stepmother, and daughter had made accusation after attending a Girl Scout's four-hour retreat on Stranger Danger. Client sentenced to 30 days of community service, not required to register as a sex offender.

Not guilty verdict in several assault in the fourth degree-domestic violence cases.
