Prosecutors say the May attack started outside Isailovic's house in Gilbert's exclusive Carriage Parc Estates. Isailovic misidentified Jarvis, who is White, as someone she thought assaulted a friend more than a year earlier, and gang members ran outside to get even. Before the sentencing, prosecutors played an unedited videotape of a Dec. 10 Devil Dogs party in which participants brawled in a drained swimming pool, flashed White power gang signs and shouted racial slurs.

He had been charged in two other unprovoked Devil Dog assaults, but those charges were dismissed as part of a plea bargain. Those older kids, he told Keppel, included his brother Mike and his girlfriend's brother, Jovan Isailovic.
