Cheng was seriously injured in an
automobile crash in Santa Clara, California, on November 4, 2008, while returning from his brother's memorial service. Cheng was traveling with his sister, Mae, when their vehicle flipped three times after hitting another car travelling at 60 mph. Cheng, who was in the passenger seat, was not wearing a
seat belt and was ejected from the vehicle. Mae was wearing a seatbelt and sustained minor injuries. She attended to Cheng, holding his head until two off-duty
paramedics rendered aid. They were able to
insert a tube into Cheng's throat to help him breathe until the ambulance arrived, an action that doctors later said helped him survive. The crash left Cheng in a
coma. In February 2009, Deftones announced that they would perform as scheduled at the
Bamboozle Left music festival in April, with their friend
Sergio Vega (formerly of
Quicksand) filling in for Cheng on stage. Vega eventually became Cheng's full-time replacement up until 2021. The website Oneloveforchi.com was created in March to help raise funds for Cheng and his medical expenses, where fans could donate to help towards an initial target of $20,000 (later raised to $50,000, $100,000 and then again to $500,000 in 2010). Fans could also read personal blogs and comments from the Cheng family, and record a message that would be played to Cheng to further speed his recovery. In late April,
PETA announced that 20% of the income from a "Happy Families, Not Happy Meals" T-shirt designed by Chi would go to the One Love for Chi foundation. There was also a "Get well soon" card on MySpace for Cheng that fans from all over the world could sign by posting comments. Fans and some rock celebrities posted comments, including
Sonic Youth,
Thursday,
The Used,
Ill Niño, and
Limp Bizkit's
Fred Durst. On April 26, 2009, Cheng was readmitted to
ICU following a near-fatal
sepsis infection; he survived the infection following treatment and was released from ICU about a week later. Following the release, a rumor started to spread in early May that Cheng had awakened fully from his coma but this was denied on oneloveforchi.com, stating that Cheng was in a
semi-conscious state. On August 18, Cheng underwent surgery to replace a bone flap in his skull that had been removed after the crash, in order to relieve
intracranial pressure. On April 27,
Shepard Fairey put three signed copies of
his Obama inauguration posters up for auction on
eBay, with the proceeds of the auction going to the One Love for Chi Foundation. Long-time friend
Fieldy of
Korn recorded an instrumental song titled "
A Song for Chi". It was released for free via
digital download on its official website where donations to Cheng and his family were also accepted. A few months later, in October, Răzvan Rădulescu (aka DJ Hefe) of the Romanian nu metal band Coma released a compilation album titled
From Eastern Europe with Love, featuring bands from
Romania,
Hungary,
Bulgaria,
North Macedonia, and
Serbia – the proceeds from the sale of the album also went to the One Love for Chi foundation. Deftones played a two-night benefit show on November 19–20 at
Avalon in Hollywood. Proceeds went to the Chi Ling Cheng Special Needs Trust. Guests included
Far,
Cypress Hill,
Rodleen Getsic,
Ben Kenney,
Greg Puciato,
Rick Verrett,
Tommy Lee,
Mike Shinoda,
P.O.D.,
Mark McGrath,
Xzibit,
Robert Trujillo,
Rocky George and
Mike Muir (
Suicidal Tendencies),
Dave Lombardo,
Alexi Laiho,
Daron Malakian,
Shavo Odadjian,
John Dolmayan, and
Max Cavalera. In May 2010, Chi Cheng began showing significant signs of improvement, and was able to track individual people with his eyes, occasionally make worded responses, and slightly move his hands. Chino Moreno stated that the Cheng family would be paying a doctor with the International Brain Research Foundation who is experienced in the field of coma and trauma patients, using funds raised through the oneloveforchi website, to use an experimental medicine to bring Chi out of his coma-like state. The treatment had an 84% success rate. Two days after being released from the hospital, in June 2012, Cheng was diagnosed with
pneumonia and rushed to the
ICU. On July 4, Cheng was released from the ICU and continued his recovery at home. ==Death==
