Adam Lanza's body was claimed several days ago by someone who wanted to remain anonymous, State Medical Examiner Wayne H. Carver II said Sunday.
Lanza's burial site also is being kept secret.
Lanza, 20, killed himself inside a classroom at Sandy Hook Elementary School in Newtown on Dec. 14 after a shooting rampage that left 26 people dead in the school, including 20 children. Lanza earlier killed his mother, Nancy, at their house.
