Sargent rented a second-floor apartment in a building owned by Ross. Anna, Sargent’s four-year-old daughter, fell from an outdoor stairway and was killed. Sargent brought suit against Ross for her daughter’s death. Ross contended that she did not have control over the stairway and therefore was not liable for its condition. Was this defense valid?
