LaMar was 15 years old at the time of her disappearance. She was walking to a bus stop near her home when she vanished.
Santa Clara County prosecutors have charged Antolin Garcia-Torres with LaMar's kidnapping and murder, but LaMar's body has never been found.
Two events have been organized for this weekend to mark the disappearance. Balloons will be released at the Sierra LaMar Search Center on Tilton Road at 9 a.m. Saturday. Later that day, a fundraiser will be held in Fremont starting at 1 p.m.
