Police say cousins Dexter "Bigg" Bowie, 17, and Johnathan "Bird" Stokley, 18, were joyriding through their neighborhood on what cops said was a stolen all-terrain vehicle last Monday night, when someone pulled an AK-47 assault rifle and fired at least 30 rounds at them, fatally wounding both teens on 9th Street near Cambria.
Relatives told the Daily News over the weekend that the boys had borrowed the ATV from a neighborhood friend.
In the wake of the killings, cops said they believed the boys were targeted. Clark said investigators are still exploring theories, but declined to elaborate.
He said that both had prior contact with police, but that he could not give details.
Family members said Bowie recently had recovered from being shot six times Jan. 5 a few blocks from where he was gunned down last week. They said they suspect the same people who shot him then are responsible for his and Stokley's deaths.
Bowie's mother, Malika "Renne" Tillman, 42, said that her son had had a truancy problem and that recently a drug-possession charge against him had been dropped, but that he wasn't a troublemaker.
"My son never did anything to make someone want to hurt him like that. He was a good kid," she said, clutching a plaque the teen was awarded for community service in 2010.
