(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.
This morning on "Early Start," CNN's David Mattingly details more in the investigation.
