The body of Newtown, Conn., shooter Adam Lanza was claimed by his father last week, a family spokesman said Monday.
Peter Lanza claimed his son's body from the Connecticut medical examiner last Thursday, said family spokesman Errol Cockfield.
“Private arrangements took place over the weekend," Cockfield said. He declined to elaborate further about the nature of the arrangements.
Connecticut Chief State Medical Examiner H. Wayne Carver, confirmed that Lanza's body is "finally gone."
Adam Lanza, 20, killed 20 first-graders and six adults at Sandy Hook Elementary School on Dec. 14 and then committed suicide. He also killed his mother in their Newtown home before the rampage.

A private funeral was held earlier this month in New Hampshire for his mother, Nancy Lanza, who was divorced from Peter Lanza.
Authorities have not offered a motive for the killings. State police say they have been exploring all aspects of Adam Lanza's life, including his education, family history and medical treatment for clues.
"Our family is grieving along with all those who have been affected by this enormous tragedy," Peter Lanza said in a statement in the days after the shooting. "No words can truly express how heartbroken we are. We are in a state of disbelief and trying to find whatever answers we can. We too are asking why."
Peter Lanza lives in Stamford, Conn., and is an executive with GE Energy Financial Services.
Adam Lanza, who was known to be very shy, had a tight relationship with his mother but was estranged from his father after the couple's 2001 separation was finalized in a 2009 divorce.

Peter Lanza had seen his son weekly after the separation, according to a family acquaintance. But Adam Lanza began refusing to see him after Peter began seeing another woman whom he later married, according to Shelley Cudiner, an employee at the library at the University of Connecticut.
Adam Lanza also began refusing to see his brother, Ryan, an accountant in Manhattan, after their parents' 2009 divorce.
