TORONTO A Toronto family was surprised to find a gravestone in the backyard of a home they purchased only months before. But Sanam Mughal and Usman Farooqui have gone from shock to pride after they did some digging and realized it could memorialize a Canadian hero. “I completely freaked out at first,” said Mughal, who said she was playing tag with her husband and son when they stumbled across the headstone. “Imagine seeing that right in the backyard next to your bedroom.” She called her husband, who had the same reaction. “I went there, I looked down to see the gravestone oh my god,” Farooqui said.
