A third man has been charged with murder in the shooting that erupted at a rally in February celebrating Kansas City’s Super Bowl win, prosecutors announced on Thursday.
Nine people have now been charged as part of the investigation into the shooting over the last five weeks, including some people accused of weapons violations. Prosecutors said on Thursday that the investigation was continuing and that additional charges were expected.
Terry J. Young, 20, of Kansas City, Mo., was charged with second-degree felony murder and unlawful use of a weapon, as well as two counts of armed criminal action.
The shooting occurred after a parade on Feb. 14 through the downtown area and a rally in front of Union Station, an Amtrak hub and tourist spot. As the rally began to disperse, several groups of people became involved in a confrontation, and as the argument escalated several people who had brought guns to the parade fired shots at one another.
Twenty-five people were shot, including one 43-year-old woman, Elizabeth Galvan, a D.J. and radio host who died from her injuries. Many of the people who were shot were children.
Two Missouri residents, Dominic Miller and Lyndell Mays, have already been charged with murder.
According to charging documents, Mr. Young was identified on video surveillance after the shooting. As the argument unfolded, Mr. Young pulled out a gun, advanced toward at least one person and fired several times, the authorities said.
He was identified on video by a distinctive backpack, the authorities said. The backpack appeared to display a bear that is half green and half yellow.
It was not immediately clear if Mr. Young had retained a defense lawyer.
Two teenagers were charged in February with resisting arrest and “gun-related” offenses in connection with the shooting, officials said. Earlier this week, one of those teenagers was arraigned on an additional charge of unlawful use of a weapon, a felony.
On Thursday, the juvenile prosecutors said that a third teenager had been charged in connection to the shooting. The 15-year-old teenager was charged a day earlier with unlawful use of a weapon for firing a gun at the rally. The three teenagers have not been identified publicly.
Jean Peters Baker, the Jackson County prosecutor, said in a statement that the investigation into the shooting was unusually broad and complex.
“We get complicated cases, but this case has been challenging,” she said.
Last week, three men were charged with firearms trafficking and other crimes as part of the investigation.
Though many people in Kansas City remain shaken by the shooting at the Super Bowl rally, a St. Patrick’s Day parade took place last weekend as planned. Attendance appeared smaller than in previous years, some spectators said.
