A Navy subcontractor pleaded guilty Friday in Rhode Island for his part in what federal prosecutors say was a kickback scheme that cost the Navy millions of dollars.

Russell Spencer's plea was part of an agreement with prosecutors in which he promised to cooperate with authorities as he has been since investigators approached him in June 2010.

Spencer, 56, pleaded guilty to conspiring to commit bribery in helping funnel money, through his businesses, from a Navy contractor to a civilian Navy employee who prosecutors say then bumped up funding to the contractor. Prosecutors say the scheme cost the Navy between $7 million and $20 million.

The case prompted an internal Navy investigation that resulted in military officials in Washington suspending the contracting authority of Newport's Naval Undersea Warfare Center. The Navy said a host of contracting problems at the facility enabled the scheme.

According to the government, Ralph M. Mariano of Arlington, Va., who worked at the warfare center, initiated the scheme by threatening to use his position to reduce funding for contracts held by Advanced Solutions for Tomorrow if company owner Anjan Dutta-Gupta didn't kick back money to Mariano.

Dutta-Gupta, of Roswell, Ga., has pleaded guilty to paying $8 million in bribes over more than a decade. Mariano has been charged, but not indicted. He has declined to comment on the allegations, and remains free on bond.

A California woman who initially claimed ignorance about the contents of multiple suitcases she was bringing to Ohio faces up to 10 years in prison Friday when she is sentenced in a $3 million marijuana shipping scheme.

After her arrest in in June 2010, Lisette Lee told investigators she planned to visit a boyfriend and transport equipment to a horse farm. She also said a friend paid her $60,000 to take suitcases from Los Angeles to an unattended hotel room in Columbus, stay for a few days and return with fewer pieces of luggage, the government said.

Lee later told investigators that she and her entourage knew the horse story was phony and that they were likely involved with "weapons and money laundering or something," authorities wrote in court papers.

Lee, 29, pleaded guilty in February to one count of conspiracy to distribute and possess with intent to distribute more than 2,000 pounds of marijuana.

In a letter to U.S. District Court Judge Algenon Marbley earlier this week, Lee said she deeply regretted getting involved in drugs.

The former International Monetary Fund head charged with trying to rape a Manhattan hotel maid formally said he was innocent of the charges Monday in his first court appearance in the case in two weeks.

Dominique Strauss-Kahn pleaded not guilty in a strong voice at the brief proceeding, standing between his defense team as his wife, journalist Anne Sinclair, watched.

State Supreme Court Justice Michael Obus went through the formality of telling Strauss-Kahn he needed to appear in court and had a right to be present at his trial, to which the economist said "yes."

The French diplomat appeared in court for the first time since he was released on $6 million in cash bail and bond last month. He has been under house arrest that includes 24-hour monitors and armed guards, first in a downtown Manhattan apartment and now in a deluxe, $50,000-a-month Tribeca town house.

About 50 hotel workers bused in by their union gathered outside the courthouse to jeer Strauss-Kahn, many wearing their work uniforms. They shouted "shame on you" as he arrived, and again as he left in a black sport-utility vehicle.

The driver of a low-cost interstate bus service was charged with four counts of involuntary manslaughter Friday following a brief court appearance on another charge stemming from this week's crash in Virginia that killed four passengers and injured dozens more.

Kin Yiu Cheung, 37, of Flushing, N.Y., had been free on bond, but he was arrested on the new charges shortly after appearing in Caroline County court Friday morning. Cheung was in court to answer to a misdemeanor reckless driving charge stemming from the Tuesday crash on Interstate 95 about 30 miles north of Richmond.

The new charges are felonies, each carrying a sentence of up to 10 years in prison.

"It's never easy to make determinations to bring serious charges, but there was enough evidence to bring the charge," Caroline County Commonwealth Attorney Anthony Spencer said after Cheung's arrest.

Police say Cheung was fatigued when the Sky Express bus he was driving swerved off the highway shortly before 5 a.m., hit an embankment and overturned. It had departed Greensboro, N.C., Monday night bound for New York City with 58 people.

Cheung's lawyer, Murray Janus, called the wreck a "tragic accident," adding he had not had time to talk to Cheung after his latest arrest.

Convicted killer Gayland Bradford was executed Wednesday for the $7 robbery-slaying of a Dallas grocery store security guard almost 23 years ago.

In a final statement, Bradford, 42, thanked friends for being with him "through thick and thin."

"I am at peace," he said. "We have no worries, just as I have no more worries. To the victim's family, may you be at peace also."

As the lethal drugs took effect, he gasped a couple of times, then began snoring, each breath progressively fainter. Nine minutes later, at 6:25 p.m., he was pronounced dead.

Bradford already was on parole for a robbery conviction when he was arrested for gunning down 29-year-old Brian Williams four days after Christmas in 1988. The shooting came on Williams' second day on the job at the market a few miles south of downtown Dallas.

Williams' mother and brother were among the people in the death chamber, watching through a window just a few feet from Bradford.

"We have no anger towards Mr. Bradford and forgive him of his crime against our family," Williams' brother, Gregory, said in a statement released following the punishment. "We now turn our thoughts and prayers to Mr. Bradford's family and friends and pray that God will give them the strength, comfort and understanding as they now grieve the loss of their loved one."

The U.S. Supreme Court last week refused to reconsider an appeal they rejected earlier, clearing the way for Bradford to become the fourth Texas prisoner executed this year. Three more lethal injections are set for this month in the nation's busiest capital punishment state.
