San Francisco District Attorney Brooke Jenkins is trying to transfer two children, both 16 years old, to adult court. The case comes just over a month before voters will decide whether to keep Jenkins in office, and marks the first time in at least several years that the city’s prosecutors have attempted to move a kid out of the juvenile system, which is supposed to be more rehabilitative than the adult one.Jenkins may also be considering moving a third child to adult court—the 17-year-old who shot 49ers receiver Ricky Pearsall near Union Square in August.
