The Supreme Court has again reinstated the conviction of a California woman for shaking her 7-week-old grandson in a case that has become a tug-of-war with the federal appeals court in San Francisco.

Shirley Ree Smith was convicted in December 1997 and was sentenced to 15 years to life in prison.

After California appeals courts ruled against Smith, the 9th U.S. Circuit Court of Appeals overturned the conviction in 2006. The appellate judges said they found "no demonstrable support" for the prosecution's theory of the case. Prosecutors said that Smith lost her temper when Etzel Dean Glass III began to cry and shook him to death.

In 2007, the high court ordered the 9th Circuit to reconsider its decision based on a recent Supreme Court ruling. In that case, the justices overturned another ruling by the appeals court that was favorable to a convicted killer.

The Massachusetts parents accused of killing their 4-year-old daughter by overdosing her with prescription drugs will be tried separately.

Assistant District Attorney Frank Middleton said in court Wednesday that prosecutors decided to hold separate trials for Carolyn and Michael Riley after the judge ruled certain statements each of the Rileys made might incriminate the other and could not be heard. Those statements could be used in separate trials.

The judge on Monday denied a defense motion to dismiss murder charges against the Rileys. Their lawyers argued that the murder indictment should be thrown out because a new medical report from a prosecution expert acknowledges that the girl had pneumonia. The defense claims that caused her death.

A 25-year-old man has pleaded not guilty to setting a fire at a western Massachusetts home that killed two of his neighbors. It was one of nine fires set within hours of one another in the community of Northampton.

Anthony P. Baye was ordered held without bail Tuesday at his arraignment on two counts of murder, arson and armed burglary in Northampton District Court. He has not been charged with the other fires.

Prosecutors said in court that Baye was caught on surveillance video in the area the night of the fires. They said that proves his alibi — that he was visiting his girlfriend — was a lie.

The Dec. 27 blaze killed 81-year-old Paul Yeskie Sr. and his 39-year-old son, Paul Yeskie Jr.

Baye lives in the Yeskies' neighborhood. A woman who answered the phone at the Baye home Tuesday declined to comment.

A man unhappy with a judge's ruling in his divorce case returned to the court house on Wednesday and shot and killed one of its employees, authorities said.

The alleged killer — a 57-year-old Austrian male — was arrested after gunning down a 42-year-old court employee who is the mother of two young children, police said. No other injuries have been reported at the district courthouse in Hollabrunn, a town about 30 miles (50 kilometers) northwest of Vienna, Austria's capital, said Leopold Etz of the Lower Austrian criminal police force.

Etz could not immediately confirm local media reports that the woman had been shot in the head. He said the motive of the unidentified attacker was not immediately clear but that he apparently had come to the courthouse for a divorce-related matter.

Wilhelm Tschugguel, president of a court in the town of Korneuburg that oversees the Hollabrunn court, said the alleged killer was unhappy with the outcome of his divorce proceedings and had entered the court in Hollabrunn to find the judge who had handled the case.

Two Riverside County men have been found guilty of murdering an 18-year-old girl, putting her body in a 55-gallon drum and leaving it in a field in Southern California.

Two separate Riverside Superior Court juries on Monday convicted Jeffree Buettner of Menifee and Glen Jones of Wildomar of the 2002 murder.

Prosecutors say Buettner and Jones beat and strangled Stephanie Benton because they thought she was talking to law enforcement about other crimes the men had committed.

Her decomposed body was found in a drum in a Lake Elsinore field with a leather belt around her neck and duct tape wrapped around her head.

The juries also found special circumstances that make the men eligible for the death penalty.
