In a hearing before the 9th U.S. Circuit Court of Appeals, Deputy Attorney General Daniel Powell argued that a judge's demand for a $250 million down payment violates state sovereignty and federal law. A court-appointed receiver wants that money to go toward his $8 billion plan to build seven new medical and mental health facilities for the state's 33 adult prisons.

Powell told the three-judge panel that the plan goes far beyond what's needed to remedy the prison health care system. The state cited proposed amenities such as therapy rooms, basketball courts and bingo boards. Powell added that the state already has taken steps to improve care that has been ruled unconstitutional.

The demand for billions to improve inmate medical care comes during a time of "extreme fiscal crisis," the state argued. California is struggling to bridge a $42 billion budget gap, furloughing employees two days each month, cutting billions from education and social services and considering a variety of tax increases.

The judges in the cases said the evidence was overwhelmingly contrary to the parents' claims — and backed years of science that found no risk.

"It was abundantly clear that petitioners' theories of causation were speculative and unpersuasive," the court concluded in one of a trio of cases ruled on Thursday.

The ruling, which was anxiously awaited by health authorities, was a blow to families who have filed more than 5,000 claims for compensation through the government's Vaccine Injury Compensation Program. The claims are reviewed by special masters serving on the U.S. Court of Claims.

To win, the families' attorneys had to show that it was more likely than not that the autism symptoms in the children were directly related to a combination of the measles-mumps-rubella shots and other shots that at the time carried a mercury-containing preservative called thimerosal.

But the court concluded that "the weight of scientific research and authority" was "simply more persuasive on nearly every point in contention."

The court still has to rule on separate claims from other families who contend that rather than a specific vaccine combination, the lone culprit could be thimserosal, a preservative that is no longer in most routine children's vaccines. But in Thursday's rulings, the court may have sent a signal on those cases, too:

"The petitioners have failed to demonstrate that thimerosal-containing vaccines can contribute to causing immune dysfunction," a judge wrote about one theory that the families proposed to explain how autism might be linked.

Wayne Tompkins was pronounced dead at 6:32 p.m. Wednesday after he failed to get courts to listen to his claims of innocence. He was put to death by lethal injection for the murder of 15-year-old Lisa DeCarr, who disappeared from the Tampa home she shared with Tompkins and her mother on March 24, 1983.

Her mom and others thought she had run away, but her body was found a year later under the home's porch. She had been strangled with the belt of her pink bathrobe.

Despite a flurry of last-minute court appeals, Tompkins' attorneys were unable to get a court to issue a stay so they could perform more DNA testing.

The shot that killed the lawyer was fired at point-blank range shortly after 9 a.m. Wednesday, Northampton Township Police Chief Barry Pilla said.

The victim worked at Terry D. Goldberg & Associates. Police did not immediately release his name because not all of his family had been notified. He died at St. Mary Medical Center in Langhorne.

No arrests had been made as of early Wednesday evening and no motive was known. Police are seeking the public's help, Pilla said.

"We're specifically interested in anyone that may have been traveling north or south on Buck Road in the vicinity of the scene between 8 o'clock, 7 o'clock in the morning until 9, 9:15," Pilla said.

Police plan to stop motorists in the area Thursday morning in hopes of finding someone with information, Pilla said.

Police stopped someone driving a vehicle similar to the one the gunman fled in and questioned him, but determined later Wednesday that that person was not the gunman.

John Reich, director of the Office of Thrift Supervision, said that by doing so, thrifts "would be supporting the national imperative to combat the economic crisis." But cooperation with the request is voluntary.

The Obama administration plans to spend $50 billion to combat foreclosures of owner-occupied middle-class homes, but is divulging few details. An announcement of the administration's housing plans is expected in the coming weeks.

"We're urging them to do it, but we're not going to try to force anyone to comply," said William Ruberry, a spokesman for the thrift agency. "We thought it was reasonable -- because the details (of the government's plans) are expected to be imminent."

Thrifts differ from banks in that, by law, they must have at least 65 percent of their lending in mortgages and other consumer loans -- making them particularly vulnerable to the housing downturn.

Some of the largest thrifts have collapsed over the past year. The failure of Seattle-based Washington Mutual Inc. in September was the largest bank collapse in U.S. history. IndyMac Bank, a Pasadena, Calif.-based thrift, failed last July in a prelude to the broader financial crisis that erupted in September.

The institutions regulated by the Office of Thrift Supervision range in size from small community banks to big institutions like ING Bank, part of Dutch financial giant ING Groep NV.

Thrifts are being closely examined by federal inspectors for signs of heavy exposure to declining markets, or troubled areas such as construction and real estate loans.

Twenty-five U.S. banks failed last year, far more than the previous five years combined, and nine banks have failed so far this year. It's expected that many more banks won't survive this year amid the pressures of tumbling home prices, rising mortgage foreclosures and tighter credit. Some may have to merge with other institutions.

Corrections officials said Tuesday they are struggling with their response to a tentative federal court ruling this week that the state must remove as many as 57,000 inmates over the next two or three years.

The state's 33 adult prisons now hold about 158,000 inmates. But the judges said overcrowding is so severe it unconstitutionally compromises medical care of inmates, and releasing prisoners is the only solution.

"We are just now beginning to have discussions (about) who these types of inmates would be. Then, how do we get to that number?" said Matthew Cate, secretary of the state Department of Corrections and Rehabilitation.

The department has no contingency plan, he said, other than appealing to the U.S. Supreme Court once the ruling becomes final.

The judges said their ruling does not amount to throwing open the cell doors.
