Analysis of information sources in references of the Wikipedia article "Emmett Till" in English language version.
Some claimed that Till had made 'indecent advances' and wolf-whistled at a white woman, Carolyn Bryant, whose family owned the store. Emmett Till's mother, Mamie Till-Mobley, however, rejected this assertion, saying that her son sometimes whistled when he got stuck pronouncing a word (she gave, as an example, bubblegum.)
Emmett, she said, had a speech impediment. She'd taught him to whistle softly to himself before pronouncing his words, in order to help with his articulation. He'd been ordering bubble gum in the store. Till-Mobley was convinced he'd merely been trying to do so with clarity.
