Maryland's Columbia mall shooter identified
Police in the US have identified the gunman who killed two people at a shopping centre in Maryland.
Darion Marcus Aguilar, 19, arrived at the centre with a Mossburg 12-gauge shotgun, Howard County Police Chief William McMahon said.
Police were trying to determine whether he knew the victims, who worked at the mall. After shooting them, Aguilar then turned his gun on himself.
"There are a lot of unanswered questions," Mr McMahon said.
The incident took place at a mall in the Baltimore suburb of Columbia.
Aguilar, from College Park, Maryland, arrived at the centre just after 10:00 (05:00 GMT) on Saturday.
He killed the victims at a store on the upper level of the Mall of Columbia, Mr McMahon said.
The victims - Brianna Benlolo, 21, and Tyler Johnson, 25 - worked at a skateboard shop called Zumiez.
It took a long time to identify the gunman since he was carrying ammunition and a backpack which police thought may have contained explosives, Mr McMahon said.
"When we originally found the shooter, he still had a lot of ammunition on his person,'' he added.
A further five people were injured in the incident. They have since been discharged from hospital.
The centre, about 45 minutes' drive outside Washington DC, is a popular weekend shopping destination.
