COLUMBIA, Md. (WUSA9) -- Police say they have not found a connection between the Columbia Mall shooting suspect and the victims.
Darion Marcus Aguilar, 19, of College Park, has been identified as the Columbia Mall shooter. Montgomery County Public Schools confirmed that Aguilar graduated from Blake High School in Silver Spring.
Police say he shot and killed Brianna Benlolo, 21, of College Park, and Tyler Johnson, 25, of Mt. Airy, Md., inside of the Zumiez skate shop.
Police say Darion Aguilar had no criminal history, but investigators have seized a personal journal from his home in College Park, which may help establish motive.
Less than three hours after the bloodshed, Aguilar's mother filed a missing person report on her son. Investigators became concerned for the 19 year-old's safety after reading an entry from his journal.
Aguilar used a Mossberg pump action shotgun, police said. Six to eight shots were fired during the chaotic scene.
"Detectives also reviewed video of Aguilar's entrance to the mall after he was dropped off by a cab around 10:15 a.m. yesterday. They tracked his movement and found that he stayed in a generally confined area before the shooting in the Zumiez at 11:15 a.m.," police said.
In addition to the two deaths, another person was shot in the foot and four other people suffered minor injuries. They were all treated and released from Howard County General Hospital on Saturday.
"Police have interviewed a victim who was shot in the foot during the incident. She advised that she was on the lower level of the mall below the Zumiez store when she received the injury. Police believe Aguilar fired between six and nine shots inside and outside of the Zumiez store and at least one of those shots fired down to the lower level, striking the victim in the foot. Four other people sustained minor injuries from medical conditions or from falling in the rush to get away from the scene," officials said in a news release.
The mall remains closed until they can regroup after this incident. It will reopen Monday at 1 p.m.
"Mall patrons who left personal property in the mall's common areas can pick them up at 30 Corporate Center, also known as the PNC Building at 10440 Little Patuxent Parkway, near the mall between noon and 5 p.m. Grief counselors will be available for those picking up property over the next few days. The mall management team will be contacting retailers directly today to schedule appointments for them to access their businesses. Anyone with an emergency situation related to property left inside the mall should call the mall's Public Safety Office at 410-730-3302," police said.
