PART 2 of 2 PARTS During yesterday's hearing, D.C. police Detective George H. Darley, of a special gun interdiction unit, said the incident that led to the arrest of the youth began about midday New Year's Eve during a routine surveillance by D.C. police and federal agents of the Bureau of Alcohol, Tobacco and Firearms at a gun dealership in Temple Hills. According to Darley's account, two young men arrived at the store driving a 1980 Ford Pinto with D.C. license plates and went inside. There, a D.C. police officer saw the 17-year-old buy a box of 12-gauge shotgun shells. While the 17-year-old was talking with the clerk, the youth mentioned his "AK," which the officer took to mean an AK-47 assault rifle. A short time later, the youth bought an unspecified number (less than a full box) of what Darley described as "live, AK-47 tracer rounds," which give off illumination when they are fired, making their path visible. In subsequent conversation, the clerk told the youth, " `If you wait a minute, I'll get you your gun,' " Darley testified. The two men soon left the store, with the youth carrying a box. Officers followed the Pinto back into the District and tried to stop it at East Capitol Street and Minnesota Avenue, but the car sped off, leading police on a chase to 20th and C streets NE, where the car stopped in the middle of the street and the two occupants ran off, Darley testified. The youth was captured at 19th and D streets NE after a brief chase on foot, Darley said. He testified that the ammunition was found between the driver's seat and the passenger seat, and that the box the youth was seen carrying was seized from the rear hatchback area of the car. The box contained a MAC-11, the serial number of which had been obliterated, Darley testified. Officers later went to the youth's home in the Trinidad neighborhood and seized five loaded weapons from the youth's bedroom and a closet in an adjacent hallway, Darley testified. *****[NOTE THE FOLLOWING -- the AK-47 "contained *two* fully loaded magazines -- how? - LT] He said the AK-47 assault rifle contained two fully loaded magazines and four more fully loaded magazines were found in a nearby box. Another MAC-11, this one fully loaded, a loaded .45 caliber automatic pistol, a loaded 12-gauge shotgun and a loaded .22 caliber pistol also were seized, Darley said. *****[NOTE THE FOLLOWING PARAGRAPH - EVEN A .45 IS A "MACHINE GUN" IN D.C. -- LT] Under D.C. law, four of the weapons, the AK-47, the two MAC-11s and the .45, are considered machine guns because they can fire 12 or more rounds without reloading. The detective said that because it was a holiday, officials had been unable to check records on the guns. No additional information about the incident was available.
