The 19-year-old gunman who opened fire at a FedEx site in Indianapolis, killing eight workers before taking his own life, was a former employee of the facility, but his motive for the rampage remained unknown, police said on Friday.
The incident — the latest in a spate of at least seven deadly mass shootings in the United States over the past month — unfolded at a FedEx operations center near Indianapolis International Airport in Indiana after 11pm local time on Thursday night, police said.
It lasted only a couple of minutes and was already over by the time police responded to the scene, Craig McCartt, the Indianapolis police department's deputy chief, told a news briefing on Friday.
Witnesses described a chaotic attack, as the gunman opened fire in the parking lot before entering the facility and continuing to shoot, leaving victims both inside and outside the building. Officers found the suspect dead of an apparent self-inflicted gunshot wound.
