According to reps from the Clark County coroner's office in Nevada, Tintor "died from thermal injuries due to a motor vehicle collision."
The officials added other contributing causes to the death included "inhalation of products of combustion, fractures of the nasal bones, right sided ribs, and left forearm, and a left hemothorax."

As we previously reported, Ruggs is accused of drunkenly causing the accident ... after officials say he was speeding with a .161 BAC before he rammed his sportscar into the back of Tintor's RAV4 at around 3:39 a.m. on Nov. 2 in Las Vegas.
In 911 calls, obtained by TMZ Sports, you can hear witnesses telling dispatchers the fire surrounding Tintor's car following the collision was intense.
"It's almost all gone," a woman said of Tintor's fire-engulfed vehicle ... adding, "and I think someone is in it."
Ruggs has been hit with five charges -- including four felonies -- for his alleged role in the crash ... and prosecutors say he's facing over 50 years in prison if he's convicted on all counts.
