MOSCOW, November 28 - RAPSI. A Moscow district court refused on Monday to issue in absentia an arrest warrant for U.S. citizen Nanette Craver on charges of murdering her adopted son Vanya Skorobogatov, the Russian Legal Information Agency (RAPSI) reports from the courtroom.

The Prosecutor General's Office objected to the investigators' request for the arrest warrant, as bringing charges against her and placing her on the international wanted list would be unlawful.

The district court began to consider the Investigative Committee's request to issue an arrest warrant for the Cravers in absentia on Monday.

The committee had already placed the Cravers on the international wanted list.

Nathaniel Craver (Vanya Skorobogatov) from the Chelyabinsk region died on August 24, 2009 in a U.S. hospital from a head injury. The numerous other injuries on his body should be considered torture, the prosecution said during the trial. Doctors found over 80 injuries on the boy's body.

The Court of York County, Pennsylvania, sentenced the Cravers on November 18 to 16 months in prison for involuntary manslaughter in their adopted son's death.

However, they were released immediately after the trial as they had spent over 1.5 years in prison.

The seven-year-old boy's death sparked public outrage in Russia and the United States.

The Foreign Ministry expressed outrage over the sentence and called it inadequate.

After the "provocatively lenient" sentence, Investigative Committee head Alexander Bastrykin issued instructions "to accelerate the investigation in order to strengthen the evidence of the Russian boy's premeditated murder committed with grave cruelty," the committee reported.
