A young Indiana mother was shot dead in front of her fiancé after she reportedly told a group of Black Lives Matter supporters ‘all lives matter’ over Fourth of July weekend.

Jessica Doty Whitaker, 24, was taking a stroll with her fiancé, Jose Ramirez, and two others near the Indianapolis Canal Walk around 3am on July 5.

Ramirez says that the four of them were hanging out when one of them used a slang version of the n-word, Fox 59 reports.

But a group of people nearby, reportedly comprised of four men and one woman, objected to hearing the phrase and a confrontation ensued between the two sets of strangers.

During the argument, the offended individuals reportedly shouted ‘Black Lives Matter’, to which either Whitaker or someone else responded ‘All Lives Matter.’
