In the wake of the deadly Kansas City shooting that erupted at the end of the Chiefs’ Super Bowl parade, the record homicide rate in Missouri’s largest city and the state’s gun laws have received renewed attention.

One person was killed and 21 others were injured after gunshots were heard outside Union Station on Wednesday as Chiefs fans were leaving a parade and rally, according to police.

Authorities detained two juveniles during the investigation and no charges have yet been filed, according to Kansas City police.

A third juvenile who had been detained in connection with the shooting was determined not to be involved and is no longer in custody, a police spokesperson confirmed to ABC News Thursday night.

More than 800 law enforcement officers were on duty at the time of the shooting, Kansas City Mayor Quinton Lucas said during the briefing.

In 2023, the Kansas City Police Department’s daily homicide analysis showed 182 homicides, 12 more than took place in 2022 and three more than the city’s previous all-time high of 179 homicides in 2020.

KCPD’s daily homicide analysis report indicates that the majority of homicides reported in 2023 involved a firearm.

When asked about Kansas City’s homicide rate in relation to Wednesday’s mass shooting, the mayor drew attention to the difference between everyday crime and this public attack.

“I grew up in some of the most troubled neighborhoods in Kansas City; usually if you didn’t get in trouble, trouble didn’t come to you,” Lucas said in an interview with KSHB after the shooting.

“This is quite different, it’s something where a group of people are in a parade. They’re not buying or selling drugs, they’re not subject to retaliation,” he added.

Lucas, who was present at the Super Bowl parade, called the shooting “an incredible disappointment.”

In 2021, Missouri had the ninth-highest rate of gun deaths in the U.S., according to state gun mortality data from the Centers for Disease Control.

The Midwestern state also has some of the laxest gun laws of any U.S. state, according to the Giffords Law Center to Prevent Gun Violence, which ranks Missouri as the third-weakest state for gun laws. .

Missouri began allowing gun owners to carry concealed weapons in 2003, which required training and a permit issued by the county sheriff; However, in 2007, the law requiring a permit to purchase a gun was repealed, according to the Giffords Law Center.

After the permit law was repealed, there was an estimated 47.3% increase in firearm homicides, according to research by the American Journal of Public Health.

There is no background check required for Missouri residents to purchase a firearm and there is no ban on assault weapons, according to Missouri state law.

In February 2023, the Missouri House of Representatives voted against banning minors from openly carrying firearms without adult supervision in public. The proposal failed by 104 votes in favor and 39 against.

“While it may be intuitive that a 14-year-old has no legitimate purpose, it doesn’t actually mean he’s going to harm anyone. We don’t know that yet,” Rep. Tony Lovasco said in response to the decision at the time, according to AP. “Generally speaking, we don’t charge people with crimes because we think they’re going to hurt someone.”

In 2021, Missouri established the “Second Amendment Preservation Act,” which created additional protections for the right to bear arms and penalizes police for enforcing federal gun laws.

However, in 2023, United States Federal District Court Judge Brian Wimes ruled that Missouri’s law was unconstitutional, “invalid, null, void and of no effect,” according to his decision.
