A Pennsylvania man was found guilty Saturday in the 2009 killings of three Pittsburgh police officers who responded to his mother's 911 call about an escalating argument.

The jury deliberated for just over three hours before returning the verdict against 24-year-old Richard Poplawski. He was found guilty of all 28 counts he faced. He was found guilty of first-degree murder in all three killings, the three most serious charges he faced.

About 50 Pittsburgh police officers lined the hallway outside Allegheny County Judge Jeffrey Manning's courtroom and burst into applause when Deputy District Attorney Mark Tranquilli emerged.

Poplawski did not comment as he was taken from the courtroom, and the judge ordered his mother, Margaret, removed as well after she stood up. Manning said he was concerned she was about to create an outburst and had sheriff's deputies remove her as a precaution.

As a result, Margaret Poplawski was not immediately available for comment after the verdict.

The trial now enters a penalty phase in which the jury will hear evidence about his mental state, background and other factors before determining if Poplawski gets the death penalty or life in prison without parole.

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.
