In Elk Grove, California, police are investigating a shooting on Friday that killed a 65-year-old man and left his 78-year-old friend in critical condition. Police believe the shooting may have been a hate crime. Both men were Sikhs and were wearing traditional Dastar headwear. They were killed while taking their daily walk. The Sacramento Valley chapter of the Council on American-Islamic Relations has offered a $5,000 reward for tips. The group noted that Sikhs are often mistaken for Muslims.
