The white SUV pauses in the middle lane as Berry begins walking in the opposite direction. The SUV flips a U-turn and begins following Berry slowly. As Berry walks down the sidewalk, the SUV appears to speed up, before running onto the sidewalk. Berry runs, the SUV close on his heels.

DPD put out a request for information on its blog Saturday afternoon. By Saturday night, they received the tip they needed. The car that hit Berry was parked outside 2109 Prichard Street.
Eventually, Lakinta Cosby arrived at the house. DPD gang unit officers arrested her. Later, according to DPD, she confessed that she ran Berry over after a domestic dispute. She’s been charged with murder.
Cosby, currently in Dallas County Jail on $100,000 bond, has a long, if nonviolent history with DPD. According to county records, she’s previously been convicted of giving a cop a fake ID, driving without a license, theft and prostitution.
