Eleven Chiefs Super Bowl Parade Victims Aged 6 to 15, Officials Say

Eleven kids between the ages of 6 years old and 15 years old suffered wounds during Wednesday afternoon's shooting at the Chiefs' Super Bowl parade, officials say.

Lisa Augustine, a spokesperson for Children’s Mercy Kansas City, said in a statement to TMZ Sports the hospital treated 12 patients after at least one gunman opened fire at Union Station following the championship festivities in K.C. -- and of those dozen, 11 were children.

Augustine added that nine of the 12 sustained gunshot wounds.

Thankfully, the hospital rep said, "All are expected to recover."

So far, law enforcement says 22 people in total were struck by gunfire just minutes after Patrick Mahomes and Travis Kelce had addressed the massive crowd that had gathered to celebrate their recent victory over the San Francisco 49ers.

At least one person, authorities said, died in the shooting.

Cops say three people have been detained in connection with the attack ... although no motive has been revealed. An investigation remains ongoing.

The Chiefs said in a statement they're "truly saddened by the senseless act of violence that occurred outside of Union Station at the conclusion of today's parade and rally."

"Our hearts go out to the victims, their families, and all of Kansas City," they added.
