Mildred Hetmanski dies after tree branch falls on her at Cantigny Park

CHICAGO (WLS) -- Mildred Hetmanski, 83, who was injured by a fallen tree branch at Cantigny Park earlier this month, has died from her injuries.

Hetmanski and three others were hurt when a huge branch from a 200-year-old burr oak tree fell on them on June 8.

The elderly woman was in the intensive care unit at Northwestern Memorial Hospital when she died on Tuesday. The Cook County Medical Examiner said she died of multiple injuries from the falling branch and ruled her death an accident.

Park officials said they do not know what caused the branch to snap from the tree. Cantigny spokesperson Phil Zeteda said the tree is one of the oldest in the park.
