NEW YORK (CBSNewYork)– A 17-year-old boy was fatally stabbed in the Bronx on Friday, police said.

“I lost my baby son,” the grieving mother, Angela Ducasse, told 1010 WINS’ Darius Radzius. ¬†

Ducasse said her life was shattered by the murder of her 17-year-old son Carl. The high school senior was about to graduate this month, but after a dinner on Friday he went out with a friend to get a milkshake and never made it home alive, CBS2’s Brian Conybeare reported.

“I fight with him ’cause I never wanted him to go outside. He went five minutes and he’s gone,” Ducasse said.

Police¬†confirm the botched robbery happened just a block from the family’s home on Walton Avenue and 175th Sreet. The family said two suspects asked him for $2 and when Carl said he didn’t have the money, one of the suspects pulled out a knife and plunged it into the victim’s heart.

“For $2, he took his life,” his mother said.

Dozens of relatives and friends gathered near a candlelight memorial outside the victim’s apartment. Carl’s uncle said he was a good kid who loved baseball and wanted to be a lawyer.

Police told CBS2 they know who the suspect is, but will only say he is a 17-year-old from Brooklyn who was still on the run as of Saturday evening.
