SAN FRANCISCO, Calif. -- Officials have confirmed that the body found in the stairwell is that of 57-year-old Lynne Spalding.

Spalding had gone missing two weeks after coming in for an infection.

Her body was found by an employee in the rarely used exterior stairwell Tuesday morning. It's not known how long the woman had been on the stairway -- which is used as a fire escape -- or how she got there.

A spokesman for Spalding's family says city officials have a lot of explaining to do.
