The businessman, Kazuyoshi Miura, was arrested Friday in the U.S. territory of Saipan as he tried to pass through immigration control at the airport to take a flight home. Miura, 60, was convicted in Japan in 1994 of killing his wife, Kazumi Miura, but the verdict was overturned 10 years ago.

"Given that this case has been closed in Japan, the Justice Ministry and Japanese police should no longer have to respond to requests from the police for evidence or to cooperate with the investigation," said Miuri's lawyer, Shinichiro Hironaka.

Miura and his wife were visiting Los Angeles on Nov. 18, 1981, when they were shot in a parking lot. Miura was hit in the right leg, while his 28-year-old wife was shot in the head. The shooting caused an international uproar, in part because he blamed the attack on robbers, reinforcing Japanese perceptions of America as violent.

The arrest came after cold-case detectives from the Los Angeles Police Department worked with authorities in Saipan and in Guam, police said in a statement. Police did not make details on the arrest available.

At a bail hearing Monday in Saipan, Miura told the court the killing "took place several decades ago, and it is unlikely that I will destroy evidence or run away," according to the Kyodo News Agency.

The court, however, denied him bail. A preliminary hearing was set for March 5, said Rosie Ada, deputy clerk at Superior Court. An arraignment was also slated for March 10, she said.

Steve Warshak, whose conviction was reported Friday by The Cincinnati Enquirer, is founder and president of Berkeley Premium Nutraceuticals, which distributes Enzyte and a number of products alleged to boost energy, manage weight, reduce memory loss and aid restful sleep.

Television ads for Enzyte feature "Smiling Bob," a goofy, grinning man whose life gets much better after he uses the product, which allegedly boosted his sexual performance.

Warshak, 40, could face more than 20 years in prison and his company could have to forfeit tens of millions of dollars.

Messages seeking comment from Warshak's Boston attorney Martin Weinberg and Assistant U.S. Attorney Anne Porter were left at their offices Friday night.

Prosecutors claimed customers were bilked out of $100 million through a series of deceptive ads, manipulated credit card transactions and the company's refusal to accept returns or cancel orders. They said unauthorized credit card charges generated thousands of complaints over unordered products.

Warshak's mother, Harriett Warshak, also was convicted of conspiracy, bank fraud and money laundering.

The government also alleged the defendants obstructed investigations by two federal agencies.

Some former employees, including relatives of Warshak, pleaded guilty to other charges and cooperated with prosecutors. They testified that the company created fictitious doctors to endorse the pills, fabricated a customer-satisfaction survey and made up numbers to back claims about Enzyte's effectiveness.

Defense lawyers characterized that testimony as tainted because it was forced by the threat of prosecution.

The defense contended in the trial that Berkeley suffered from customer service that didn't keep pace with the company's rapid growth from a one-person startup in 2001 to 1,500 employees in 2004.

Weinberg also had told jurors that Berkeley had been targeted by the government in "a relentless criminal investigation."

Polk County, Fla., sheriff's officials said they were asked to speak with "the father of the shooting suspect" — Robert Kazmierczak of Lakeland, Fla.

The gunman is the younger Kazmierczak, a university official told The Associated Press on condition of anonymity because the identity has not been released by police.

The motive of the killer, who graduated from NIU in 2006, was still not known as the investigation unfolded Friday, officials said. The gunman also wounded 15 people in Thursday's attack, which sent panicked students fleeing for the exits.

"There is no note or threat that I know of," NIU President John Peters said on Friday ABC's "Good Morning America." "By all accounts that we can tell right now (he) was a very good student that the professors thought well of."

DeKalb County Coroner Dennis J. Miller released the identities of the four victims who died in his county: Daniel Parmenter, 20, of Westchester; Catalina Garcia, 20, of Cicero; Ryanne Mace, 19, of Carpentersville; and Julianna Gehant, 32, of Meridan.

Two other victims died after being transferred to hospitals in other counties, Miller said. Winnebago County Coroner Sue Fiduccia said a female victim died in her jurisdiction but has not been identified pending notification of family.

Witnesses said the gunman, dressed in black and wearing a stocking cap, emerged from behind a screen on the stage of 200-seat Cole Hall and opened fire just as the class was about to end around 3 p.m. Officials said 162 students were registered for the class but it was unknown how many were there Thursday.

Allyse Jerome, 19, a sophomore from Schaumburg, said the gunman burst through a stage door and pulled out a gun.

"Honestly, at first everyone thought it was a joke," Jerome said. Everyone hit the floor, she said. Then she got up and ran, but tripped. She said she felt like "an open target."

"He could've decided to get me," Jerome said. "I thought for sure he was gonna get me."

The shooter had been a graduate student in sociology at Northern Illinois as recently as spring 2007, but was not currently enrolled at the 25,000-student campus, Peters said. He also said the suspect had no record of police contact or an arrest record while attending Northern Illinois, about 65 miles west of Chicago.

The former police chief of Luthersville pleaded guilty Tuesday and was sentenced to five years in prison for charges stemming from sexual encounters with two women last year, prosecutors said.

The case against police Chief David Yates began with a rape accusation from a 21-year-old woman in August.

Then it grew when another Luthersville woman came forward, saying she twice had been coerced into sex with Yates in 2007 because the chief promised leniency against her husband in a drunken-driving case.

Yates pleaded guilty to one count of false imprisonment and two counts of violation of oath of office, said Pete Skandalakis, the district attorney for the judicial circuit that includes Meriwether County, 45 miles southwest of Atlanta.

After his prison term, Yates will be on probation for five years and has to register as a sex offender.

Another ex-Luthersville officer arrested in the case, Jason Hardegree, avoided prison but got five years probation after pleading guilty to giving false statements and violation of oath of office. He had agreed to testify against the chief if the case went to trial.

Skandalakis said both pleas were negotiated as the case was set to go before a grand jury next week.

In the rape case, on Aug. 24, Yates went to the 21-year-old woman's home in uniform and with his patrol car and threatened to have her young daughter taken from the home by child-welfare authorities if she didn't have sex with him, Skandalakis said. The chief admitted the sex took place, but said it was consensual, the prosecutor said.

A week or so earlier, he unsuccessfully tried to get her committed to a mental hospital after she made repeated unwanted calls to a friend of Yates' who she had just stopped dating.

After Yates was arrested, the other woman, 26, reported her story to authorities, Skandalakis said. She said that she had sex with Yates twice —- including once in a vacant home —- between March and July 2007 in exchange for leniency in her husband's DUI case.

Hardegree had a much lesser role in the incident involving the 21-year-old; he tried to prevent the woman from pursuing criminal charges against Yates and made a false statement to investigators, Skandalakis said.

Louis Eppolito, currently in federal custody, faces sentencing May 9 in U.S. District Court here. The maximum penalty in the case is three years in prison and a $250,000 fine.

Greg Brower, U.S. attorney for Nevada, said that according to a plea agreement, Eppolito and his wife, Frances, filed a tax return for 2000 that reported income of just over $127,000 when their actual income was more than double that amount.

Brower said Eppolito also failed to declare $175,000 in income from screenplay writing in 2001 and 2002.

Eppolito and another former New York detective, Stephen Caracappa, were accused of participating in at least eight mob-related killings while working for the Luchese crime family. The two detectives retired in the early 1990s and moved to Las Vegas, where they were arrested in March 2005.

In 2006, a New York jury found the pair guilty of a racketeering conspiracy responsible for multiple murders and other crimes. Two months later a federal judge dismissed that case after determining that the statute of limitations had expired for the racketeering charges, which allegedly occurred from 1986 and 1990. The judge's decision is under appeal.

The men still face drug and money laundering charges.

Eppolito's 1992 autobiography, "Mafia Cop: The Story of an Honest Cop Whose Family Was the Mob," details his police career and his Mafia connections.
