They confirmed that Darrell is dead, and didn't ID release the name of the other band member yet. Police don't release names until next-of-kin are notified, and since Vinnie was Darrell's brother, he would be the one notified, and therefore the police could release info immediately.
Eyewitnesses say that the guitarist (Pat Lachman, also in Halford and Diesel Machine,) was shot four times, which means that he's most likely the other band member who died.
The bouncer who tried to pull the gunman off of Lachman was also shot at close range.
