A Mother’s Day cookout in Lawrence, Kansas ended in fatal violence on May 11, 2014. Charles T. Brockman, 26, attended a gathering at an apartment complex after receiving threatening text messages related to an ongoing dispute with another man over a woman. Witnesses said Brockman arrived armed with a shotgun and chased the other man toward a second-floor staircase, prompting panic among adults and children at the event.

As Brockman moved up the stairs, the other man—reported to be armed with a handgun—fired multiple shots. Brockman was struck and taken by family members to Lawrence Memorial Hospital, where he died from his wound before transfer to another facility. Police questioned the shooter but no arrests or charges have been announced and no suspects have been publicly named.

Who has information about the dispute or the shooting that could help fill the gaps in this case?
