In re Matthew W.
Annotate this Case
A juvenile wardship petition (Welfare and Institutions Code section 602(a)) alleged that Matthew had committed assault with a deadly weapon and assault by means likely to produce great bodily injury; that Matthew had personally inflicted great bodily injury on the victim and had caused the victim to suffer great bodily injury resulting in paralysis and had personally used a deadly weapon, a knife. The juvenile court found true all of the allegations except for the paralysis enhancement; dismissed count two and the accompanying enhancement, at the request of the prosecutor; declared Matthew a ward of the court; and placed Matthew on probation with conditions.
The court of appeal reversed, finding that Matthew’s pre-arrest statements to police were made during a custodial interrogation without the required Miranda warnings and that the admission of those statements was prejudicial. While Matthew was told at the start of the interrogation that he was not under arrest, and the police officers who were present did not handcuff him or unholster their weapons, the interview was initiated by police, who had just heard from another that Matthew had stabbed the victim. The entire interrogation was an attempt to get Matthew to admit that he stabbed the victim and to provide additional incriminating information.
