A Pennsylvania mother of three collapsed and later died after completing a half marathon Sunday.
Lindsay Doherty had just crossed the finish line of the race in Scranton when she lost consciousness.
Heroic resuscitation efforts failed to revive the 36-year-old, who was pronounced dead after she was rushed to Geisinger Community Medical Center.
The Roman Catholic Diocese of Scranton, where Doherty worked as development officer, released a statement on the tragedy as her loved ones waited for an autopsy to determine the cause.
"Lindsay was a bright, energetic young woman and a devoted wife and mother," Bishop Joseph Bambera said in the statement. "Our thoughts and prayers are with her husband, three young children, her parents and her family.
"May God comfort them and may she rest in the blessing of His peace."
According to local reports, Doherty ran the 13.1-mile race last year with a time of 1:55:32 after taking up running a couple of years ago.
"This is a difficult and tragic situation and on behalf of the race committee and all of the runners who participated today, we extend our deepest sympathies and ask everyone to keep this family in their thoughts and prayers," race organizers said in a statement.
The Lackawanna County coroner said an autopsy was planned for Monday to determine the cause of death.
