Investigators have said the problem comes from tainted wheat gluten imported from China.

The lawsuit, filed in U.S. District Court for the Southern District of Florida on behalf of three cat and dog owners in Michigan and Florida, names 15 food companies and retailers as defendants, including Menu Foods, P&G and Wal-Mart Stores Inc.

In a press release, the law firm said the companies have spent $300 million a year in marketing campaigns that misrepresent the contents of their pet foods.

An Iams spokesman could not immediately be reached for comment.

According to court documents, the 34-year-old Rock told police she shot 36-year-old Kenneth Walkinshaw at their home in March after he complained about how bad his life was.

Police say the couple had argued earlier, and that Rock said Walkinshaw had tried to choke her.

State Police began investigating the case after receiving information from the Washington County attorney's office indicating that the settlement money may have been improperly used.

State Police Senior Investigator Thomas Aiken said the client had been hurt in a car crash, but had been on Medicaid. The county had placed a lien against the check, but never received the money despite the check being cashed in December.

"They were owed compensation (by the client) but they never got it," Aiken said. "The bulk of it (the check) was supposed to go to the county, with whatever was left over going to the client."

Washington County Attorney Roger Wickes was not available Wednesday morning.

The arrest is the latest legal problem for Oswald, who was Washington County public defender for 3.5 years until resigning in August 2005, days before he was arrested on a bad check charge. That charge was later dropped.

He was arrested last summer on a charge he burglarized a female acquaintance's home in Kingsbury, but said recently that the felony charge in that case was dropped. He also was ordered to spend 15 days in Washington County Jail last month for not paying $11,000 in child support.

Oswald was free on bail Wednesday but could not be reached for comment Wednesday. The phone number listed for his law office was disconnected as of Wednesday morning.

A disciplinary arm of the Ohio Supreme Court has temporarily suspended the law license of a Cincinnati attorney who was addicted to marijuana and cocaine.

Ken Lawson has handled many high-profile civil rights cases in Cincinnati.

He acknowledges that he was addicted to drugs for years and that it affected his job performance. Several clients have sued him, accusing him of mishandling their cases and failing to show up for court dates.

The Supreme Court's disciplinary counsel is reviewing a complaint filed by the Cincinnati Bar Association. The case could take months to complete.

The court could decide to revoke Lawson's license permanently.

Lawson says he's been clean since February First and is participating in a rehab program.

The charges grew from the bribery scandal that landed former U.S. Rep. Randy "Duke" Cunningham in prison.

Foggo and Wilkes now face 30 wide-ranging counts of fraud, conspiracy and money laundering. Each faces more than 20 years in prison if convicted, prosecutors said.

Prosecutors claimed in their earlier 11-count indictment that in fall 2003, while he was working as a logistics officer at a CIA supply hub overseas, Foggo arranged a $1.7 million contract for one of Wilkes' companies to be a middleman in supplying bottled water to the agency.

The new indictment outlines a second scheme in which Foggo is suspected of providing Wilkes with "sensitive, internal information related to our national security," including classified information, to help him prepare bids for providing undercover flights for the CIA under the guise of a civil aviation company and armored vehicles for agency operations.

Foggo, who was the agency's executive director at the time, is also charged with encouraging his CIA colleagues to hire Wilkes without disclosing that the pair were childhood friends.

Prosecutors say that in return, Wilkes offered to hire Foggo after he retired from government service and treated his friend to extravagant meals and vacations, including a trip to Scotland during which they racked up a $44,000 hotel bill and took $4,000 helicopter rides to play golf.

Wilkes was charged in a separate indictment with conspiracy, bribery, money laundering and unlawful monetary transactions to Cunningham in return for government contracts.

A new indictment was returned in that case last week that included new charges against another defendant, New York mortgage banker John T. Michael, who was described as a co-conspirator in Cunningham's 2005 plea agreement. Michael now faces counts of money laundering and unlawful monetary transactions in connection with wire transfers allegedly used to pay off the mortgage on Cunningham's $2.5 million mansion.

Wilkes and Michael pleaded not guilty to the new charges. All three men remain free on bail.

U.S. District Judge Larry Burns set a Sept. 18 trial date for Wilkes and Michael, followed by a trial for Foggo and Wilkes starting Oct. 23. Burns denied a request by Foggo's attorneys that their client be tried separately in Virginia, where he lives.

Burns also heard arguments from defense attorneys on several key issues, including a request for an investigation into government leaks to news organizations including The Associated Press during the probe.

Wilkes' attorney, Mark Geragos, has said he believes the information was leaked to pressure Justice Department officials into approving criminal charges sought by prosecutors in San Diego before ousted U.S. Attorney Carol Lam resigned in February. The indictments were returned two days before her departure.

"It's clear - clear to me at least - that they were scrambling," Geragos said after Monday's hearing. "It sure looks to me as though something's going on in that office, and I don't know what it is."

Prosecutors have said that the timing had nothing to do with Lam's departure. Assistant U.S. Attorney Jason Forge told the judge the matter had been referred to another U.S. attorney's office as part of an internal Justice Department review.

Burns ordered that the results of the review be turned over to him and said he would require the government to disclose to defense attorneys the identities of any witnesses who had been identified as leakers.

The initial charges came 20 months after the FBI opened an investigation into Cunningham, who served on key House committees with oversight of government contracts. He pleaded guilty in November 2005 to taking $2.4 million in bribes from defense contractors and was sentenced to more than eight years in prison.

Foggo and Wilkes played high school football together growing up in Chula Vista, south of San Diego. They roomed together at San Diego State University, were best men at each other's weddings and named their sons after each other.

Foggo, the former No. 3 official at the CIA, resigned from the spy agency in May 2006 after his house in suburban Virginia and office at the CIA's Langley, Va., headquarters were raided by federal agents.

Kaplan, along with 10 other executives from the online gambling industry were indicted by U.S. District Court in St. Louis on charges that the company took billions in illegal bets from U.S. residents. The company BetOnSports stopped taking bets from US citizens as a result of a civil settlement last November, and agreed to return the money back to the American bettors, something that has not happened as of yet. The criminal charges, however, are still pending.

The 48-year-old Gary Kaplan was arrested in March in the Dominican Republic, after fleeing the country to avoid prosecution.
