REVEALED: What triggered Super Bowl parade shooting that claimed two lives

Two men have reportedly been charged with murder for shooting at the Super Bowl victory parade in Kansas City that claimed a life and injured more than 20 others last Wednesday, BBC reported.

And the reason it started was because someone was looking at someone else.

NBC News reported that, according to court documents, the shooting took place due to an altercation between four men.

Reports said, "Four males approached Lyndell Mays, and one of the males asked Lyndell Mays what he was looking at; because they didn’t know him, they began arguing about why they were staring at each other."

The charged men, identified as Dominic Miller and Lyndell Mays, were both shot and wounded during the incident.

Prosecutor Jean Peters Baker of Jackson County said at a press conference on Tuesday that the two men had been charged with second-degree murder, two counts of armed criminal action, and unlawful use of a weapon.

And are being held on a $1 million (£792,000) bond.

Baker said Mays first drew out the gun, followed by other people, including Miller, who prosecutors believe is the one who shot and killed Lisa Lopez Galvan, 43, during the incident.

Surveillance footage of the shooting shows that Mays approached the other group aggressively and pointed at them "in an angry manner" before drawing his weapon.
