Tyshawn Lee loved to play basketball and video games. On Monday he was in an alley in the Gresham neighborhood, according to Chicago police. Witnesses said an argument broke out and that's when the boy was shot.
Tyshawn was hit multiple times in his upper body and died in the street.
Investigators haven't been able to discern a motive for the slaying, Chicago police detective Dean Andrews said at a news conference, adding, "We will be working around the clock to find out more."
Visibly distraught, the boy's mother, Karla Lee, spoke to reporters Tuesday. She asked anyone with any information about the shooting to step forward. She held a photograph of her son and a football.
"Please put the guns down, please," Lee begged between tears. "I'm only 26. This is my only baby."
A small memorial with stuffed animals and a basketball appeared in the alley where the boy was killed.
As detectives canvassed the area and interviewed neighbors, saddened and outraged residents were determined to do what they could.
Some handed out fliers asking anyone with information about Tyshawn's killer to contact police. The flier said a reward would be given.
Crisis responder Dawn Valenti told reporters that donations for that reward had reached $20,000 as of Tuesday evening.
Tyshawn's death happened on the same day Democratic presidential candidate Hillary Clinton met
in Chicago with parents whose African-American children have died in shootings.
