Edelman is repping the family of Adam Lanza, who killed 26 people, including 20 children, during his Dec. 14 rampage at Sandy Hook Elementary School in Newtown, Conn.

Errol Cockfield Jr., a politico who joined the No. 1 independent PR firm last year and is a VP, serves as spokesman for the Lanza family.

He served as spokesperson for former New York Governors Eliot Spitzer and David Paterson. Cockfield moved to Edelman from his chief of staff perch for New York State Senate Minority Leader David Sampson. He was previously Albany bureau chief for Newsday.

The PR firmís connection to the Lanza family is via Adamís father, Peter, who is VP-taxes in General Electricís financial services unit. GE is an Edelman client.

Peter retrieved his sonís body from Connecticutís medical examinerís office on Dec. 27. Adam also killed his mother, Nancy. She was divorced from Peter.
