Mohammad Faisal, a family friend, said a bearded Muslim entered the shop Shah operated on Friday afternoon. They spoke. Then the man stabbed Shah in the head with a knife, Faisal said.
Faisal said Shahâ€™s brother, who was at his job next door, came in the shop to find the attacker sitting on his brotherâ€™s chest, laughing.
