MEMPHIS, Tenn. — WREG is examining who is responsible for reporting suspicious activity they see on social media.

Disturbing pictures of murder suspect Kwasi Corbin have been blasted across televisions and social media after police said he admitted to firing an automatic rifle into a crowd of people downtown, killing Myneishia Johnson, a teenage mother just days from her high school graduation.

All of these images come from a public Facebook page — anyone can see them — and WREG has learned it appears even some of Corbin’s family members knew about them.

WREG has done more digging and discovered there were plenty of other people who say they’re victims of his violent crimes.

“I call them a walking time bomb. Just waiting to explode,” said Jimmy Chambers, who works in the District Attorney’s Gang Unit.

Alarming pictures posted on 19-year-old Corbin’s Facebook are one sign of his reported violent behavior.

According to a police report, an ex-girlfriend filed domestic assault charges against him after he allegedly beat her up in March. He’s accused of threatening another ex-girlfriend in September with a gun. Southaven Police said he also faces other domestic violence charges out of their jurisdiction. And Memphis Police said he threatened and beat up a teen over a basketball game.

This alleged radical behavior is obvious on social media. Videos and pictures of Corbin flashing guns and cash are virtually everywhere.

“I was at a seminar recently where it was said that ill behavior unaddressed becomes accepted behavior,” said Len Edwards with COMEC, the Commission on Missing and Exploited Children.

Edwards spends his days talking to parents dealing with troubled teens. In a year when the youth homicide count is rapidly rising, he said parents need to be held accountable. If they see suspicious behavior from their child, they must do something.

Interim Police Director Mike Rallings recently weighed in, too.

“I’m gonna ask that parents make sure that their children are actively engaged in something productive,” said Rallings.

Edwards said the strict parenting needs to start when children are young, but even for teens there’s no reason why a parent shouldn’t do something to stop their child from a destructive lifestyle.

“There’s a lot of excuses. There’s a lot of explanations for why things are the way they are, but the reality of it is I know a lot of single parent moms raising multiple children in a very healthy and disciplined home.”

Edwards said it’s a parent’s responsibility but also said it’s up to neighbors and friends to do something, too. If you think something is off, notify police. If you see something, say something.
