The deadly Kansas City Super Bowl parade mass shooting that left one dead and over 20 shot stemmed from a personal dispute that ended in gunfire, police said.

Kansas City Police Chief Stacey Graves emphasized that the shooting at the west end of city’s landmark Union Station Wednesday was not a terror attack.

Police initially took three people in for questioning after the deadly assault, which law enforcement sources said was not terrorism-related.

Despite this, it’s not clear what spurred the shootings – or if the parade-goers were the primary target or just an unintended consequence of community violence.

Their bullets wounded 22 people – including nine kids – and killed mother-of-two Lisa Lopez-Galvan, a dedicated Chiefs fan who reportedly died from a shot to the abdomen.

“She was the most wonderful, beautiful person,” Lisa Lopez, a longtime friend (of no relation) who works as its newsroom executive administrative assistant, told the Kansas City Star.

The mass shooting ruined what was an otherwise joyous celebration commemorating the Chiefs’ recent Super Bowl victory over the San Francisco 49ers.

Hundreds of thousands of people turned out for the parade – until the gunfire sent panicked crowds scurrying for cover.

“I’m angry at what happened today,” Kansas City Police Chief Stacey Graves told reporters at a press conference. “The people who came to this celebration should expect a safe environment,”

“Because of bad actors, which were very few, this tragedy occurred even in the presence of uniformed law enforcement officers,” she said, noting there were some 800 cops deployed in the area at the time of the shooting.

A heroic Chiefs fans ran down and tackled one person who may have been a gunman before cops took them into custody, according to one video making the rounds on social media.

Graves said her department was working to determine whether the person in the video was a person they have in custody.
