SCRANTON, Pa. (AP) — A coroner says a woman who collapsed at the end of a half marathon in Pennsylvania died of an internal hemorrhage.

The Scranton Times-Tribune (http://bit.ly/2nx5NNl ) reports that the Lackawanna County coroner said Monday that 36-year-old Lindsay Doherty died of intra-abdominal bleeding.

The married mother of three collapsed at the end of Sunday's 13.1-mile (21.1-kilometer) Scranton Half Marathon. Emergency medical personnel tried to revive her at the race before she was taken to a hospital.

The Roman Catholic Diocese of Scranton says Doherty worked in its development office, raising money for Catholic education. A special prayer service was scheduled Monday night at St. Paul's Parish in Scranton.

The Scranton resident had run the half marathon the previous year.
