A Colorado man driving his pregnant wife to the hospital to deliver their third child crashed and died after apparently suffering some kind of medical problem.

The Colorado State Patrol says 37-year-old Tony Schmucker died after his Nissan Pathfinder went off the road and down an embankment west of Fort Collins early Wednesday. The wife and the couple’s two sons, who were also in the SUV, all survived.

37-year-old Tony Schmucker reportedly had a medical emergency while taking his wife Jill Schmucker to a hospital on Wednesday. Tony Schmucker died after the couple and their children got into a car crash 

According to a family fundraising website, Jill Schmucker suffered a broken back but delivered a baby boy by cesarean section at the hospital.

Coroner’s investigator James MacNaughton told the Coloradoan that initial findings suggest a medical event, and not injuries from the crash, caused his death.
