A little before 11 am on a Sunday morning, Ranjeet Singh was at the gurudwara in Wisconsin where he played the tablas every Sunday during the kirtan or hymns at the prayer service. Ranjeet was 45. On weekdays, he did a salesman's job at a general store, scraping together to send some money home to his wife and his son, Gurvinder, who he last saw 16 years ago. His son was seven months old then.
