The center released a statement explaining that the shooting occurred in the parking lot.
"Our hearts go out to the families who have suffered loss on this tragic day," read the statement in part. "Our heartfelt gratitude as well to all those in Kansas City and around the world who have expressed sympathy, concern and support."
With the play scheduled to start, and being the eve of Passover, which starts Monday, the community center was busy when the shooting broke out.
Edward Dannewitz, who said his child was in the center when the attack happened, was shocked to hear what happened.
"We dropped our daughter off for dance practice and took our other daughter to Chuck E Cheese. The next thing you know, we're seeing updates on the phone saying that there's a shooting at the JCC," he said. "I figured this was one of the safest places I could drop my kid off at, and apparently it's not."
Rabbi Arthur Nemitoff, senior rabbi at The Temple, Congregation B'nai Jehudah, located about a mile from the Jewish Community Center told ABC News that police arrived after the shooting around 1:45 p.m. and have stationed a police car there as a precautionary measure.
Kansas Rep. Kevin Yoder said he was "heartbroken" over the shootings.
"Brooke and I send our prayers and thoughts to the families and victims of this tragedy and our office stands ready to provide any needed assistance," Yoder said in a statement.
As a matter of protocol the Los Angeles Police Department has stepped up patrols around Jewish-oriented locations. The New York Police Department said it was already in a heightened state of alert due to Passover holiday.
