PITTSBURGH — Authorities in Western Pennsylvania say a runner who collapsed and died during the half-marathon competition of the Pittsburgh Marathon had an inherited abnormality of the coronary artery system.

The Allegheny County medical examiner's office said an autopsy Monday on the body of 23-year-old Kyle Johnson of Pittsburgh revealed the abnormality in the system that supplies oxygen to the muscles of the heart.

Dr. Karl Williams said such defects are rare but are associated with sudden unexplained deaths, such as the 1988 death of NBA star Pete Maravich.

Public safety officials said the runner collapsed near paramedics at the 12-mile mark of Sunday's race and was later pronounced dead at UPMC Marcy.

RED LION — A transgender student in central Pennsylvania will be allowed to wear a boy's colors to next month's graduation ceremony but will be identified by his female name, a resolution the American Civil Liberties Union said Monday doesn't go far enough.The ACLU of Pennsylvania released a letter from a lawyer for the Red Lion School District summarizing its handling of the student, who uses the name Issak Wolfe but is enrolled as Sierra Stambaugh. The teenager, a senior at Red Lion Senior High School, says he plans to undergo a physical transition.Wolfe said he was disappointed the district refused to honor his wishes and request for a broader nondiscrimination policy.“I want to make sure that future transgender students are not humiliated and disrespected the way I was,” he said in a statement provided by the ACLU.
