A college in Pennsylvania is mourning the tragic loss of a student-athlete. Angel Mercado, a baseball player for Division II Central Penn College, died this week while working on dismantling a makeshift dugout.

According to the Associated Press, Mercado was playing in a summer recreation league in a park in Harrisburg, Pennsylvania. The coach of Mercado’s team had built a makeshift dugout there out of wood on Sunday. The city said the dugout was not allowed, and Mercado was part of the group dismantling the structure on Monday.

The dugout collapsed unexpectedly and Mercado was struck in the face. Two volunteers were seriously injured. Mercado’s death has been ruled accidental by the Cumberland County coroner’s office.

“Nothing criminal happened here,” city spokesperson Matt Maisel said, via the AP. “No charges will be filed against the coach. No charges will be filed against anyone. This is simply a tragedy.”

Central Penn College President Linda Fedrizzi-Williams wrote a letter to students remembering Mercado and sharing the information for a GoFundMe page set up by his college coach, Robert Stern.

“As friends who have become family, we are mourning the heart-wrenching loss of one of our own, a promising young athlete who senselessly lost his life while helping others enjoy the sport he loved so much,” Fedrizzi-Williams wrote. “No words can adequately express our anguish.”

Mercado had completed his freshman season. He was 19.
