Shortly after 7-year-old Kenneth Rosario aimed a basketball at a hoop at Don Bosco School in Matunga, he collapsed in front of his classmates and had died by the time he was taken to a nearby hospital yesterday.

The Std II boy was reportedly healthy before the incident and his sudden death has flummoxed both his parents and school authorities. Even the initial post-mortem has not been able to throw much light on the cause of death.
