Metro’s chief information officer retired abruptly last month, the first top executive to leave the agency since Metro’s new chief executive officer became the agency’s permanent leader. Suzanne Peck had previously been chief technology officer for the District before joining Metro in 2007. A key fundraiser for Vincent Gray, and later transition team adviser, she was apparently considered for a top appointment when he won the mayoral election. But the Metro announcement noting her departure did not list any future plans.

Peck did not return a call for comment Friday afternoon. Her retirement was first reported by The Washington Times.
