Police: Maryland mall shooter expressed "unhappiness" with life
There are new details about the shooting at a Maryland mall over the weekend.
Darion Aguilar shot and killed two employees at a skateboard shop before turning the gun on himself.
The co-owner of the United Gun Shop where Aguilar purchased his weapon tells CNN the 19-year-old visited the shop twice in December.
On his first visit, Aguilar purchased a shotgun on for about $430 in cash, plus two boxes of ammunition.
A couple of weeks later Aguilar returned for another box of shotgun shells. But why Aguilar opened fire Saturday morning, killing two people before killing himself, remains a mystery.

What is Hillary Clinton's biggest political liability for 2016?
Fmr. U.S. Secretary of State Hillary Clinton addressed Monday potentially her biggest weakness head-on.
Clinton said Monday that the deaths of four Americans in Benghazi, Libya was her biggest regret during the four years she served as America's top diplomat.
"My biggest regret is what happened in Benghazi," Clinton said in response to a question from David Westcott, the outgoing chairman of National Automobile Dealers Association. "It was a terrible tragedy losing four Americans, two diplomats and now it is public so I can say two CIA operatives."
And with President Obama's poll numbers down in his second term, Clinton tried to distance herself from her former boss.
Clinton's biggest regret at State: Benghazi
"I had disagreements with President Bush but you know I also had disagreements with President Obama," Clinton said.
So, what's the biggest liability for a Clinton 2016 campaign - is it Benghazi or Obama?
