An internal investigation into how the officers assisted two Apple employees search the Bernal Heights' home of Sergio Calderone has begun, according to Lt. Troy Dangerfield. The exact details of that search, which took place several weeks ago but only just came to light at the end of last week, have been difficult to ascertain. First the SFPD denied involvement, then admitted to their participation.
