O’Leary has reportedly hired prominent Canadian defense attorney, Brian Greenspan.
If the name sounds familiar, Greenspan has previously represented celebrities who were in trouble, including Bieber and Noami Cambell.
Justin was accused in 2013 of punching a Canadian Uber driver in the head after a night out of partying. The charges were eventually dismissed.
The high-powered attorney also repped Naomi Campbell and Catherine Smith, who in 1986, admitted injecting John Belushi with the fatal injection of heroin and cocaine.
As we reported, O'Leary's ski boat crashed into another vessel, killing two people.
O’Leary is facing questions about statements he made following the deadly crash where he claimed the other boat took off and had no navigation lights on.
The brother of one of the victims said following the crash, he hoped that whoever is found guilty will "do the time."
O'Leary says he's cooperating with investigators in the crash and released this statement:
"Late Saturday night I was a passenger in a boat that had a tragic collision with another craft that had no navigation lights on and then fled the scene of the accident. I am fully cooperating with authorities. Out of respect for the families who have lost loved ones and to fully support the ongoing investigation, I feel it is inappropriate to make further comments at this time. My thoughts are with all the families affected."
Either way, he will need a good lawyer, and now he has one.
