A grieving mother is speaking out and hoping for justice after the fatal stabbing her 15-year-old son, Lesandro Guzman-Feliz.

The incident happened outside a bodega on East 183rd street, where police say the suspects dragged the Bronx teenager out of the store and slashed and stabbed him to death. 

Leandra Feliz says the past 24 hours have been a nightmare she can't wake up from.

“I don't know what I'm going to without him, I don't know,” she says. 

Guzman-Feliz was her youngest child.  

Feliz viewed the video of her son's horrific stabbing for the first time and was able to see the men who police say took his life.

Police aren't sure what lead to the deadly stabbing, but they believe a dispute broke out between Guzman-Feliz and the knife-wielding men.

This case has touched some local celebrities, including Cardi B, who posted to social media with the hashtag #JusticeforJunior.

Police are offering a $2,500 reward anyone for who has information on the case.
