Wednesday, the Mason County Sheriff's Office received a complaint of a reckless driver in a grey Toyota Prius on US-10 at approx. 9:13 am. The driver, 52 year old Patrick David O'Brien, from Muskegon, ended up rear ending a pickup truck which was slowing to turn into a business on US-10. Following the collision, the Prius crossed all five lanes of US-10, ran off the road and struck several trees. O'Brien was seriously injured in the crash. He was initially transported by LIFE EMS to Spectrum Health Ludington Hospital and then transferred down state with serious injuries. He will be released to the mason co jail once discharged. O'Brien was arrested June 15 for 3rd offense drunk driving. At this time it is unclear if Mr. O’Brien suffered a medical condition or if a controlled substance contributed to the crash. Drug paraphernalia was found in his vehicle and a toxicology test is pending.
