Authorities are refusing to comment on any connection between a deadly plane crash in downtown Anchorage and the fact that the pilot's wife worked in one of the buildings the plane hit.

The FBI is investigating Tuesday morning's crash that killed 42-year-old Doug Demarest during an unauthorized flight of a Cessna 172 owned by the Civil Air Patrol. Two buildings were struck in the crash.

No one on the ground was hurt, but the pilot's wife works at a law firm in one of the buildings.

FBI spokeswoman Staci Feger-Pellessier said in a statement Wednesday that FBI policy prevents commenting on an active investigation, and the agency does not expect to provide any updates for at least two weeks.

The Civil Air Patrol says Demarest was not authorized to be flying the plane when it crashed.
