He was 33.
The early reports are sketchy, but it appears Hastings was involved in a single-car accident in Los Angeles.
At 4:57 p.m., the Los Angeles Times reported: "Neither the Los Angeles Police Department nor coroner's officials could immediately confirm whether Hastings was the victim of a single-car crash that occurred about 4:25 a.m. in the 600 block of North Highland Avenue. Police officials said it was the only vehicle fatality reported Tuesday morning in the city of Los Angeles."
A witness, Luis Cortez, told KTLA News, "I was just coming northbound on Highland and I seen a car, like, going really fast and all of a sudden I seen it jackknife. I just seen parts fly everywhere and I slammed on my brakes and stopped and tried to call 911."
According to the Rolling Stone obit, Hastings' colleague and friend, Matt Farwell wrote, "Michael was no stranger to trying to make sense [of] this kind of tragedy nor was he unfamiliar the emptiness felt in the wake of a senseless, random death. After all, he'd already learned about it the only way he ever deemed acceptable for a non hack: first-hand."
While covering the war in Iraq, Hastings' then-financée was killed in a Baghdad bombing in 2007. He wrote a book about it called "I Lost My Love in Baghdad: A Modern War Story."
The world lost an important voice today. Hastings was a young, serious journalist with so many more stories to be told. We will go on, but his absence will not go unnoticed.
