Three people were killed Sunday afternoon at two different Jewish community facilities in a Kansas City-area suburb, and a man was held in custody as police attempted to discover whether or not the shootings were anti-Semitic, authorities said.

Police said it was too early to determine a motive for the shootings, but added they were not ruling out the possibility that they were a hate crime. They have called in the Federal Bureau of Investigation to assist with the investigation, Overland Park Chief of Police John Douglass said in a news conference.

"We know it's a vicious act of violence. Obviously two Jewish facilities, one might make that assumption." Douglass said.
