(CNN) - Linda O' Leary, wife of entrepreneur and 'Shark Tank' star Kevin O'Leary, has been charged with "careless operation of a vessel" for her role in a fatal boat crash in Ontario, Canada, last month, according to police.
Three other passengers were injured, including one on the O'Leary boat, according to police.
Carolle Dionne told CNN that the maximum penalty for the regulatory charge is 18 months in prison or a $1 million dollar (CAD) fine.
His agent, Jay Sures, last month said that Linda O'Leary was given a DUI test, which she reportedly passed.
Wonderful on "Shark Tank," O'Leary co-founded the software Softkey, now known as The Learning Company.
