A promising young rapper used his Twitter account to boast about speeding and drink driving - even tweeting 'YOLO' (the acronym for You Only Live Once) - moments before the car hit a wall in Ontario, Canada, killing everyone inside.
Ervin McKinness, 21, was one of five men all in their early twenties killed in the suburban crash just after 1am over Labor Day weekend.
A Twitter account linked to the Southern California rapper, known as 'Inkyy' and 'Jew'elz', contained a tweet at 1.19am on September 2 that read: 'Drunk af going 120 drifting corners #F***It. YOLO.'
The final tweet was one minute later, reading: 'Driving tweeting sipping the cup f*** yolo I'm turning it up.'
Police told the San Bernardino Sun that it might have been another rapper, 21-year-old Jonathan Watson, who was driving the vehicle at the time of the accident.
The 2005 Nissan Sentra allegedly ran a red light, lost control and slammed into a wall before coming to rest in the backyard of a home.
Four of the five passengers died at the scene with the fifth pronounced dead at a nearby hospital.
The four other passengers have been identified as Marquell Bogan, 23, Dylan George, 20, Jonathan Watson, 21, and JaJuan Bennett, 23.
The tweets have become part of an investigation by police.
'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 [drunken driving] was a cause or contributed to the crash,' Ontario police Sgt. David McBride told the SBSun.
