Jefferson was home playing video games with her nephew when they heard a noise in their back yard. She grabbed a handgun from her purse and walked toward a window. That's where Dean, who had entered her back yard investigating the call, ordered her to put her hands up before firing a single, fatal round.
Jefferson's funeral will be held at The Potter's House of Dallas at 2 p.m. on Saturday. Pastor T.D Jakes will deliver the eulogy and Rev. Al Sharpton is expected to give special remarks.
