The body of the young man who killed 26 people in the second largest school shooting in U.S. history has been claimed by his father.

A spokesman for the family said Monday that Peter Lanza claimed the remains of 20-year-old Adam Lanza.

Adam Lanza killed 20 children and six adults at a Connecticut school on Dec. 14. He also killed his mother before going on the rampage and then killed himself.

Police have not offered a motive.

The attack prompted President Barack Obama to push for "real action, right now" on gun violence.
