Hip hop mogul J Prince is sounding the alarm on an alleged Houston gang member who cops say executed his ex's daughter as revenge for a breakup ... Prince says the guy needs to be held accountable
Prince -- the Rap-A-Lot Records honcho who has a reputation for getting things done in Houston -- put the alleged killer on blast Wednesday, telling his 756k Instagram followers ... "We can't have clowns like this running around purposely killing our babies and be ok with it."
Houston police say 22-year-old Jeremiah Jones is the triggerman in a child's fatal shooting, and he's been arrested following a manhunt and booked on counts of capital murder and aggravated assault with a deadly weapon.
Cops say Jones "executed" 9-year-old Khylie Sorrells as possible "revenge" over the girl's mother breaking up with him several months ago and allegedly seeing other men.
