Prince George’s County officials, stymied by a refusal of witnesses of the illegal street race that killed eight in Accokeek to step forward, are launching a general crackdown on drag racing in the county.

Police have interviewed about 20 of the roughly 200 people who gathered around 3 a.m. on Feb. 17, on Indian Head Highway to watch an illegal road race, said Maj. Kevin Putnam, who heads the unit investigating the accident. Darren Jamar Bullock, of Waldorf, an unlicensed driver, hit 14 members of the crowd with his Ford Crown Victoria.
