Ervin McKinness, a 21-year-old aspiring rapper, tweeted about driving drunk at 120 mph minutes before dying in a fiery one-car crash that killed the rapper and four others.

Drunk af going 120 drifting corners #FuckIt YOLO — 2.7.5 Inkyy (@ink2flashyy) September 2, 2012

"YOLO" is an acronym for "You Only Live Once." The phrase was made popular by singer Drake, who used "YOLO" in his song "The Motto."

Another tweet reportedly posted by McKinness talked about drinking and driving. The tweet read, "Driving tweeting sipping the cup f*** yolo I'm turning it up," according to the Daily Mail. This tweet has since been deleted but retweeted on the account.

At 1:40 a.m., McKinness died in a crash in Ontario, Calif., at Creekside Drive and Haven Avenue when the 2005 Nissan Sentra ran a red light, skidded out of control and slammed into a wall, according to the San Bernardino County Sun. The car wound up in the backyard of a home. Marquell Bogan, 23, and Dylan George, 20, both of Ontario; Jonathan Watson, 21, of San Bernardino; and JaJuan Bennett, 23, of Rancho Cucamonga were also killed in the crash.

All were pronounced dead at the scene except Bogan, who was taken to a nearby hospital where he was pronounced dead, according to CBS News.

Despite McKinness' tweets, police reported that it was actually Watson who was behind the wheel, according to the San Bernardino County Sun. "They're certainly looking at that because it will be a vital part of the investigation, but it's too early to give an opinion as to whether it (drunken driving) was a cause or contributed to the crash," Ontario police Sgt. David McBride told the San Bernardino County Sun.

Tweets were posted on the rapper's official Twitter account this week. Whoever took over the account is attempting to clear McKinness' name.

McKinness, who went by the names Jew'elz and Inkyy, had signed a record deal, according to Vibe. An official video for his song "Dreams" was published on his YouTube channel, InkyyTV, back in April.
