(WBIR) The city of Knoxville has been acquitted of any wrongdoing in the death of a woman killed when a tree fell on her car while she was driving in South Knoxville.

The family of Tiffany Raley claimed the city was liable for her December 2011 death because it knew the tree was unsafe but didn't have it removed.

However, court documents show the Tennessee Court of Appeals ruled that because the tree was on private property, it wasn't the city's responsibility to have it removed.

In early 2012, the Raleys also filed a suit against the property owners, Brett and Barbara Johnson, for negligent and reckless behavior.
