LOS ANGELES — While setting up a chess board at a mental health treatment center in Agoura Hills, Jack Stein looked past his roommate like he'd seen a ghost. The 24-year-old went to his room, laced up his shoes and walked out into the midsummer evening.
That was the last time anyone saw him.
His sister, Zoë Kustritz, is still trying to figure out what happened.
