( CNN ) -- Officials in West Texas said Monday they are investigating the `` suspicious '' death of a 3-year-old boy , adopted from Russia , and a Russian official blamed the death on `` inhuman abuse . '' The boy was born on January 9 , 2010 , and died on January 21 , 2013 , according to Konstantin Dolgov , the Russian Foreign Ministry 's special representative for human rights . `` I would like to draw your attention to another case of inhuman abuse of a Russian child by U.S. adoptive parents , '' he said in a statement . Dolgov claimed the child suffered injuries to his head and legs , as well as to his abdomen and internal organs . The wounds , he said , `` could only be caused by strong blows . '' Kim Herrington , an investigator with the Ector County Medical Examiner 's Office , said the case was referred to his office because of the `` suspicious '' nature of the child 's death . Patrick Crimmins , of Texas Child Protective Services , said his office is investigating . The allegations include physical abuse and neglectful supervision , or neglect , he said . Sgt . Gary Duesler , spokesman for the Ector County Sheriff 's Office , said his office is also investigating . No arrests have been made , and officials are waiting for autopsy results , he said . A call seeking comment to a number listed for the boy 's adoptive parents was not immediately returned . A voice message told reporters the parents would have no comment . The child 's death comes amid tension between the United States and Russia over adoptions . U.S. State Department spokeswoman Victoria Nuland said Monday that officials are aware of the case . `` The Department of State takes very seriously the welfare of children , particularly children who have been adopted from other countries , '' she said . `` We will continue to assist the Russian Embassy and consulate officials in making contact with the appropriate authorities in Texas . '' In December , Russian President Vladimir Putin signed into law a measure that would ban the adoption of Russian children by U.S. families . It is scheduled to take effect in January . The action could affect hundreds of U.S. families seeking to adopt . Americans adopted close to 1,000 Russian children last year , according to U.S. State Department figures . Though the number has been dropping in recent years , Russia remains the third most popular foreign country -- after China and Ethiopia -- for U.S. foreign adoptions . The Russian measure also bars any political activities by nongovernmental organizations receiving funding from the United States , if such activities could affect Russian interests , Russia 's semiofficial RIA Novosti news agency said . And it imposes sanctions against U.S. officials thought to have violated human rights . The move is widely seen as retaliation for a bill that U.S. President Barack Obama signed into law on December 14 . That law , called the Magnitsky Act , imposes U.S. travel and financial restrictions on human rights abusers in Russia . The Magnitsky Act is named for Russian lawyer Sergei Magnitsky , who uncovered the largest tax fraud in the country 's history in the form of rebates claimed by government officials who stole money from the state . Magnitsky was apparently beaten to death in 2009 after a year in a Moscow detention center . Backers of the Russian bill said American adoptive parents have been abusive , citing what they say are 19 deaths of adopted Russian children since the 1990s . The Russian public supported the bill , with 56 % of respondents in a poll conducted by the Public Opinion Foundation ( FOM ) saying they backed the ban , RIA Novosti reported . In 2010 , an American woman sparked outrage after she sent her adopted son back to Russia alone on a one-way flight , saying the boy , then 7 , had violent episodes that made her family fear for its safety . CNN 's Chandler Friedman and Elise Labott contributed to this report .
