In Re Dennis M‪.‬

MOSK, J. Dennis M., a juvenile, appeals from a judgment declaring him to be a ward of the court and committing him to the Youth Authority. (Welf. & Inst. Code, §§ 725, 800.) He contends that the record is insufficient to support a finding that he was guilty of involuntary manslaughter, and that his confession was introduced into evidence in violation of the rules laid down in Miranda v. Arizona (1966) 384 U.S. 436
