At least three people were killed Saturday in a shooting inside a mall in Columbia, Md., a suburb of Baltimore, Howard County police said on Twitter.
Police said in a news conference this afternoon that the suspected shooter is believed to be one of the dead, according to NBCNews.com. They added that the shooting occurred in one store on the upper level of the shopping center.
The identities of the other victims have not yet been revealed.
Earlier, police wrote in a tweet that they received a 911 call reporting a shooting at around 11:15 a.m. Around 12:35 p.m., police posted an update saying there was "no indication of additional shots fired."
One of the three dead was found near a gun and ammunition, authorities said. Police believe the body belongs to the suspected gunman.
At this time there is no confirmed motive for the shooting, but police sources told ABC news that the shooting may have been related to a domestic dispute "involving a husband, his estranged wife, and her boyfriend."
The Columbia Mall will be closed through the night, police said.
