Crime is most unnerving when it's random, when it just doesn't make any sense.
“I can't. I haven't. I try not to think about the event and how it happened,” said murder victim Marcus Edwards’ mother. “I try not to think about it."
Because the who is hard enough, but the why can drive a grieving mother mad.
It's the reason Nicole Ausberry-Brooks, armed with poster board picture of her oldest son Marcus on his high school graduation, gathered with friends, family and law enforcement to plead with the public Wednesday.
"Devastating, devastating. I wouldn't wish this on anybody...devastating," she said.
Because it's been five months and nothing.
Edwards was studying social work at Morgan State University.
At 21, he was closing in on his degree and he desperately wanted to be a Washington, D.C. police officer.
But on Sept. 19 at 10 p.m. in Baltimore, while on the phone with his girlfriend, he was stabbed to death in the middle of Loch Raven Boulevard and police believe it was for no reason at all.
"He was not in a confrontation with anyone. His girlfriend hear what she thought was a scuffle and the last word that she heard from Marcus was someone just stabbed me," Baltimore Police Chief Stanley Branford said.
It’s a murder Branford called “pure evil,” but months have gone by with very few leads, so this group is asking the public again.
This time between the FBI and Metro Crime Stoppers, they are offering a $22,000 reward.
For Marcus' mother, closure will always remain elusive, but to know something will help.
"To know what happened...that will happen a little bit because at least I know that person cannot harm someone else. That matters yes. A whole lot. And that they are paying for the crime they did for nothing," she said.
