A candlelight vigil in honor of DEFTONES bassist Chi Cheng is planned for 6:30 p.m. tonight (Sunday, April 14) at Cesar Chavez Plaza in Sacramento, California.Chi died yesterday at the age of 42. He had been in a semi-comatose state for more than four years after being seriously injured in a car accident in November 2008. In addition to not recovering full consciousness, Cheng had been in and out of hospitals for various infections as his family has struggled with the mounting costs of care since he lost his health insurance a few months after the accident. Cheng was taken to the emergency room, where he died at 3 a.m. on Saturday. "His heart just suddenly stopped," Cheng's mother, Jeanne Marie Cheng, wrote on the OneLoveForChi.com web site. "He left this world with me singing songs he liked in his ear. He fought the good fight. You stood by him sending love daily. He knew that he was very loved and never alone." Cheng required surgery after the car accident to remove part of his brain, but his recovery was strong enough that he was taken off life support seven months later. Over the course of the past couple of years, Cheng emerged from his coma for brief intervals. He was able to open his eyes and apparently could see and hear things going on around him, but could not respond verbally. Sergio Vega continues to play bass for DEFTONES. Vega stepped in for touring purposes after Cheng's accident, and stayed on to record 2010's "Diamond Eyes" and last year's "Koi No Yokan" with the group.
