Detectives are expected to confirm next week whether anyone will be brought before the courts for the murder of schoolboy Keelan Wilson, who was stabbed to death in Merry Hill, Wolverhampton, in May 2018.
Several arrests have been made but no-one has been charged almost 18 months on.
Keelan was ambushed as he tended to a broken-down car on Strathfield Walk at around 11pm.
Police have conducted a lengthy investigation into the murder and a dossier of evidence has been provided to the Crown Prosecution Service (CPS).
It has been an anxious waiting game for mother Kelly Ellitts who admitted she will be devastated if nobody is charged.
She said: "I've got everything banking on this, I've got everything crossed. This is everything."
Ms Ellitts has been critical of police over the lack of information she has been given on the investigation but acknowledges the challenges officers have faced in their efforts to secure justice for Keelan.
She said: "I've just got to hope. This is a complex case and there are a lot of people involved and no-one wants to go to prison. I don't know what's going to happen.
"The thought of a murderer being out on the streets - it's even worse knowing they've done it to my child. They should get the worst possible punishment."
Ms Ellitts added: "I'm really anxious at the moment. I'm not looking forward the meeting in some ways, and in some ways I am. It's really mixed emotions."
If it doesn't go the way she hopes, the grieving mother insists she will keep on fighting.
"I would have to keep pushing, I would put up a reward. It's something I've been told not to do but I would do it."
