Three people were killed in a shooting spree at a Maryland mall, Howard County police said.

The victims at The Mall in Columbia included the suspected shooter, police said. A press conference was scheduled for 1:15 p.m. ET.

"Three people confirmed dead at Columbia Mall. Victims unknown at this time," the department reported on its Twitter feed.

The department, in a tweet, said the call came in to the 911 dispatcher around 11:15 a.m. that shots were fired at The Mall in Columbia. Responding officers found the bodies, including "one found near a gun and ammunition."

Police said the mall was believed to be secure, but they asked people in the mall to stay where they were until officers confirm that the mall was secure.

Ed Main was shopping at the Justice store with his son Noah, 15, his daughter Tori, 12, and his niece Ana Collins, 18, when they heard two loud pops. He said they were hustled by an employee into a storeroom in the back of the store. Main, from nearby Westminster, said, the employee "shut the door and barricaded it from the inside."

Columbia, with a population of about 100,000 people, was built in the 1960s as a planned community of 10 "villages." Columbia is about 18 miles from Baltimore and 24 miles from Washington, D.C.
