suspects identified in brutal attack

Here's news on another possible hate crime that happened last week in Delaware: Suspects Sought in Brutal Beating. Police have identified several men who attacked a 21-year-old man of Indian descent while he was pumping gas at a 7-Eleven. He was kicked, punched, and beaten with a baseball bat for no apparent reason, putting him in the hospital with serious injuries. Two of the men have been identified as Lewis Johns, 27, and his brother Cody Johns, 17. They're both charged with first-degree robbery, first-degree assault, second-degree conspiracy and possession of a deadly weapon during the commission of a felony. They're also looking for a third assailant, "Ronny," who participated in the assault: Two men identified in vicious beating. So what happened? Random attack? Just plain robbery? (They took $5 from the guy.) Hate crime?
