A married Pennsylvania mother of three who had just crossed the finish line of a half marathon she ran in Sunday suddenly collapsed and died due to a ruptured vein that led to abdominal bleeding, the coroner confirmed.

Lindsay Doherty, 36, tragically died after running in the Scranton Half Marathon.

According to the Morning Call, two emergency room physicians were at the race and attempted to revive Doherty. The woman was then taken by ambulance to the Geisinger Community Medical Center.

The Lackawanna County Coroner said that Doherty “had every shot in the world.”

“She had every shot in the world. The resuscitation was heroic. It just didn’t work, unfortunately,” Timothy Rowland said.

Rowland described the hemorrhage as a rare condition.

Doherty died in the emergency room.

Friends, family and neighbors are mourning Doherty’s loss.

"Disbelief, at first, 36 years old, you just don't think it can happen. As people started talking about it a little bit more, it started to hit home a little bit more. It's sad, just sad that it's in the community," a local, Mark Seitzinger of the Green Ridge Neighborhood Association, told WNEP.

Doherty is survived by her husband James and their three young children.
