Lee said Harris spent her days watching her siblings and, when her mother went to sleep, would take the keys to her mother’s van so she could take other teens on “joyrides.”

That is how, on the morning of Brown’s death, Harris found herself with D’Angelo Matthews, who was 16 at the time, and Christopher Shakel Williams, her 15-year-old boyfriend at the time.

The three teens and a fourth boy, who authorities have not named, stole fire extinguishers and drove around Greensboro spraying cars and people as they passed by.

Williams told investigators that the teens dropped the fourth boy off at his apartment before coming across Brown walking to a bus stop, said Guilford County District Attorney Avery Crump.

She said Williams told investigators Matthews asked him if he wanted to rob Brown and after some discussion they got out of the van and began spraying the 74-year-old with a fire extinguisher.

Williams told investigators that Brown kept walking and told the boys to stop. Matthews began hitting him with the fire extinguisher, Crump said.

She said Williams admitted to striking Brown once with the “butt” of the extinguisher.

The boys took Brown’s wallet and $3.
