Police in Maryland say three people died Saturday in a shooting at a mall in suburban Baltimore, including the presumed gunman.
Law enforcement officials told CBS News that early indications were that the shooting was not a random act. It is believed that the shooter and a victim knew each other.
The Mall in Columbia is at the center of the town, a suburb of both Baltimore and Washington.
The victims have been identified as Brianna Belolo, 21 and Tyler Johnson, 25.
According to Brianna's facebook page she attended Sand Creek High School in Colorado Springs.
The mall typically opens at 10 a.m. on Saturdays and it was not known how many shoppers or workers might have been present at the time of the shooting.
Joan Harding of Elkridge, Md., was shopping with her husband, David, for a tiara for their granddaughter's 18th birthday. She said she heard something heavy falling, followed by gunshots and people running.
"My husband said, 'Get down!' and the girl that worked in the store said, 'Get in the back,'" Harding said. That is where they hid until police gave the all-clear.
Witnesses said they heard a succession of gunshots fired near the food court on the first floor of the mall.
People were directed out of the mall and into a parking lot, where some boarded a bus and others walked toward their cars. Some people were seen crying.
Laura McKinzles of Columbia works at a kiosk in the mall. She said she heard between eight and 10 gunshots, followed by people running and screaming. She ran into the backroom of a perfume store and locked the door.
The suspect has not been identified, but police said while looking through the shooter's bag inside the store they found two devices that appeared to be explosives.
