New York police say an expectant father was killed when a device he was building for a gender reveal party exploded.

Christopher Pekny, 28, was killed when he was building the device for his child’s gender reveal party in the Catskills town of Liberty Sunday afternoon. His 27-year-old brother, Michael Pekny, was injured, police said. Michael Pekny was treated for his injuries at an area hospital.

The death is the latest in a string of tragedies blamed on faulty gender reveal devices in recent years.
