Six people were hospitalized after a large tree limb fell onto a church group holding a barbecue in a Memphis park, officials said. Three children were taken to La Bonheur Children\'s Hospital in critical condition after the incident in Overton Park Monday afternoon, and three adults were taken to various hospitals for non-critical injuries including burns from a deep fryer, The (Memphis) Commercial Appeal reported Tuesday. The reason the limb fell was not immediately clear. No names of the victims were released. \"The tree limb was as large as most trees,\" said Daniel Wakefield, Memphis Fire Department battalion commander.
