She shared a statement from the boy's mother that read: "Marcus was my third child, such a sweetheart. He loved his family. He loved music. His older brother and sister missed him every day and my grandmother took it very hard. She brings him up daily." The boy's father, Marcus Haislip Jr., is facing charges of first-degree assault, armed criminal action and unlawful possession of a firearm after authorities say he allegedly fired in 2019 at the suspect in his son's murder in an act of retaliation, Fox4KC reported previously. He remains in the Jackson County Detention Center, according to online jail records, which do not indicate whether he's entered a plea or has an attorney to speak for him.
