She last saw her son, 13-year-old Lamonne Johnson-Chisholm, lying on the sidewalk and bleeding from his back Sunday afternoon.
Since then, she's received hundreds of phone calls and Facebook messages.
“I know Monne to be an amazing person, but I would have never imagined he had that much of an effect on so many people,” says Chisholm.
Police say they have no suspects.
“I would hope the same people that are contacting me, the parents of these kids that seem to know a whole bunch about it, make it OK for their kids to talk to authorities so Monne's killers can be brought to justice,” says Chisholm.
The search for justice is something Chisholm has known before.
Her nephew, Monne's cousin, was shot down last December just a few feet from her home.
No arrests have ever been made in the murder of 16-year-old Christopher Southerland.
Police do not believe the two cases are connected, but in both, investigators need the same thing to find the killers.
They need someone to take action and call the Crime Line.
“Somebody saw something. Somebody heard something. They might not think it’s important, but it could be just that one piece to solve the case,” says Holly McPherson with the Newport News Police Department.
Meanwhile, this mother will have Thanksgiving for the first time without her youngest son, Monne.
If you know anything, you can call the Crime Line at 1-888-LOCK-U-UP.
Now the family is asking in lieu of flowers for folks to make a donation to Monne's memorial fund.
You can do so by visiting any First Advantage Bank.
