Connecticut Medical Examiner Wayne H Carver II tells the Hartford Courant newspaper that the remains of Adam Lanza were claimed several days ago by someone who wanted to remain anonymous.
A spokeswoman at Carver's office told The Associated Press she could not release details.
The 20-year-old Lanza killed 20 children and six adults at a Connecticut school on December 14. He also killed his mother before going on the rampage and then killed himself.
Police have not offered a motive for the killings.
The attack prompted President Barack Obama to push for "real action, right now" on gun violence.
Hartford: The body of the man who killed 26 people in the second largest school shooting in US history has been claimed for burial.
