Deputy DA Chad Mahalich returns to Contra Costa County Superior Court in Walnut Creek, Calif. on Thursday, Jan. 24, 2019 for the afternoon session of a hearing for Allie Sweitzer's accused killer in juvenile court. Authorities say Sweitzer, 20, was murdered in 2017 by a 15-year-old gang member and was originally ordered to stand trial in adult court but a new law that went into effect Jan. 1 says no one under the age of 16 can be tried as an adult.
