THE REGION

Federal Crackdown Federal agents arrested 16 people in the Washington area Tuesday in connection with a crackdown on the peddling of false documents in open-air markets in the Adams Morgan and Hyattsville areas, authorities announced yesterday.

Immigration and Customs Enforcement and Secret Service agents executed search warrants at four residences in the District and one in Hyattsville. At one D.C. address, agents seized a firearm, bags of fraudulent document papers, a typewriter and a laminating machine, authorities said.

MARYLAND

Handgun Charges Montgomery County police arrested three men and a juvenile who they said belong to Mara Salvatrucha, a violent street gang, after finding a loaded gun in their car.

About 7 p.m. Sunday, police said, an officer saw a blue Toyota speeding from the area of New Hampshire Avenue and Southampton Drive in the Langley Park area. Moments later, occupants in another vehicle told the officer that they had just been shot at by someone in the Toyota.

Another officer pulled over the Toyota at University Boulevard East and Merrimac Drive and found a .22-caliber semiautomatic pistol hidden in a hollow space in the car.

Police arrested Oseas Villegas Barahona, 21, of the 11600 block of Elkin Street and Elmer Rodriguez, 25, of Bel Pre Road, both in Silver Spring, and Giovanni Laebi, 20, of the 8100 block of 15th Avenue in Hyattsville. They were charged with three gun-related counts. Eduardo Flores, 17, of Wheaton was arrested and charged as an adult with having a handgun in a vehicle, having a handgun on his person and possession of a firearm/ammunition by a minor.

Man Arrested Again A Charles County man who police say had rifles, grenades and a methamphetamine lab in his home was arrested yesterday in St. Mary's County, more than two weeks after a judge ordered him rearrested.

Authorities learned that Lawrence Fox, 23, was going to be in Leonardtown outside the Joseph D. Carter government building, said Lt. Daniel Alioto of the sheriff's office. The arrest happened without incident after 1 p.m.

Fox was arrested July 19 when co-workers at Belk Department Store said he was carrying a gun. His car was searched, and he was charged with two handgun violations. A search of his La Plata home revealed a weapons cache and drug-making equipment, police said.

A District Court commissioner released Fox on his own recognizance that night because he had been told only of the two handgun charges and not about the weapons found at Fox's home. On July 22, a judge ordered that Fox be taken back into custody.

THE DISTRICT

Death Ruled Homicide The death last week of a District man has been ruled a homicide, D.C. police said yesterday.

John K. Reid, 53, was found badly beaten in his apartment in the 1500 block of F Street NE about 8:30 a.m. July 25, police said. He died at Howard University Hospital the next day, police said. The D.C. medical examiner ruled Thursday that the death was caused by a severe blow to the head, police said.

HOMICIDES

* An unidentified man was fatally shot early yesterday in Northwest Washington, D.C. police said. The man, whose name was withheld by authorities pending notification of his relatives, was found shot inside a black Ford pickup about 12:30 in the 4000 block of Arkansas Avenue NW, police said. He was pronounced dead at the scene. Anyone with information is urged to call police at 202-727-9099.

VIRGINIA

Fatal Mauling A Spotsylvania County judge refused to dismiss an involuntary manslaughter charge yesterday against a woman whose pit bulls are alleged to have killed her elderly neighbor.

Deanna H. Large, 36, will stand trial Aug. 16 on charges that she let her pit bulls run wild, resulting in the March 9 mauling of Dorothy Sullivan, 82. If convicted of the three running-at-large counts and the involuntary manslaughter count, Large could face a decade in jail.

Her attorney, Eugene Frost, noted that no one has ever been convicted of such a serious charge for a dog-related death in Virginia.

Circuit Court Judge Ann Hunter Simpson refused without comment to dismiss the involuntary manslaughter charge.

Battery Charges A Woodbridge day-care worker has been arrested and charged with two counts of aggravated sexual battery and two counts of indecent liberties with children, Prince William County police said yesterday.

Winfred M. Williams, 62, an employee of the former Young World Development Center, posted a $5,000 bond Tuesday night after his arrest that day, according to the Prince William-Manassas Regional Jail. He is accused of inappropriately touching two girls, ages 2 and 6, at the center. Williams did not return a message left at his home yesterday.

The charges stem from incidents in February that were reported by a co-worker, said police spokesman John Bogert. Williams was removed from the center March 11, he said.
