A technology company manager known for being strict to his subordinates is found dead in the very same softball court where his company’s baseball team trains every week. The deceased is tied to a metal chair, with his face bearing the marks of an attack with a baseball bat. Forensics determine that the manager was killed by a large burst of balls from the serve machine. The evidence, including DNA, places heavy suspicion on a member of staff clearly in conflict with the manager, and he confesses freely under interrogation. But the only doubt is that he is right-handed, but the murderer was using a left-handed glove, and the fingerprints on the murder weapon are not his. Could there be somebody else?
