CALIFORNIA IN BRIEF : SAN LEANDRO : Boy Admits Killing Man at High School

A 16-year-old boy admitted in court that he took part in the fatal stabbing of a Union City man who was killed last month as he waited outside a high school to pick up his daughter. The teen-ager, who cried after making his plea, was one of four youths arrested in the Oct. 17 killing at James Logan High School in Union City, a suburb of 53,000 people about 20 miles southeast of San Francisco. Thomas Weinhofer, 41, was stabbed once in the chest outside the school where his daughter was playing in a regional band competition. The youth’s plea to second-degree murder is termed an admission, or stipulation, in Juvenile Court and is effectively a guilty plea. He is scheduled for sentencing Dec. 18. Two boys, ages 11 and 13, are to appear in Juvenile Court. The 11-year-old had been expelled from school for beating a classmate.
