COLUMBUS, Ohio (CNN) -- A gunman opened fire Wednesday night during a heavy metal concert in Columbus, killing four people -- including at least one member of the band -- and critically wounding at least two others before a police officer shot and killed him, according to Columbus police.
The attacker leapt onstage as the group, Damageplan, performed, and began "targeting members in the band," Sgt. Brent Mull said.
Two others were injured in the incident, although the nature of their injuries was not clear.
According to eyewitness accounts, the gunman initially shot and killed the band's guitarist, Dimebag Darrell. Darrell, 38, and his brother, Vinnie Paul, 40, are former members of Pantera -- a group they formed in the 1980s. Their father is Jerry Abbott, a country and western songwriter and producer.
