Weapons Sentence A Prince George's County man in whose home federal agents found improvised hand grenades and ingredients for the biological weapon ricin was sentenced in federal court yesterday to 41 months in prison.

Myron Tereshchuk, 43, will serve the term after he completes a 63-month sentence imposed by a Virginia court for an extortion scheme.

Federal agents investigating the $17 million extortion plot that Tereshchuk, who ran a patent business, directed against a business competitor searched his Hyattsville home in March 2004. They found firearms, modified grenade hulls and explosive powder as well as large quantities of castor beans and other material used to make ricin. Records in federal court in Greenbelt do not suggest any link to terrorism.


Contempt Sentence A man who refused to testify before a grand jury investigating a homicide pleaded guilty yesterday in D.C. Superior Court to felony contempt and was sentenced to two years in prison, the U.S. attorney's office said.

Gregory Cunningham, 24, of the 200 block of Channing Street NE, refused to answer questions in the grand jury's investigation of the March 2003 slaying of Antjuan Thomas, though he was believed to be a witness, prosecutors said.

Prosecutors eventually brought charges in Thomas's slaying, and a defendant was convicted. Cunningham, who is serving a 12-year sentence for manslaughter in an unrelated case, will serve the two years for contempt after his manslaughter term ends.

Unlicensed Money Transfer A woman from the Republic of Guinea who came to Washington on a diplomatic visa to work in her country's embassy has pleaded guilty to running an unlicensed money transfer business that wired more than $15 million to the Middle East, Africa, Europe and Asia, authorities said yesterday.

Aissatou Pita Barry, 38, of Silver Spring pleaded guilty Monday in U.S. District Court in Washington to running the unlicensed business from 2001 to 2004. She faces up to five years in prison and a $250,000 fine, according to U.S. Immigration and Customs Enforcement.

Authorities said there was no indication that Barry worked in an official capacity at the embassy. Authorities said it was the first time a person had been convicted in the District under a part of the USA Patriot Act that targets unlicensed money-transmitting businesses.
