Police officers blocked off a large area northwest of Lacy Park after reports that a man with a gun was seen on Circle Drive, according to San Marino Police Chief John Incontro. A helicopter from the Pasadena Police Dept. was dispatched to the scene and circled over the area for more than a half hour. Four vehicles from the Alhambra Police Dept. and a San Marino police cruiser kept watch over a home at the intersection of St. Albans Road and Mill Lane, where the suspect was possibly holed up.
