Police are investigating after a young girl drowned in a swimming pool at a Wildwood hotel over the weekend. They say a six-year-old girl staying at the Nantucket Inn & Suites on Ocean Avenue went into the deep end of the pool by mistake Saturday afternoon. CPR was performed on the girl after she was pulled from the pool but she died at the hospital. Her identity hasn't been released but police say she was from Philadelphia. There is no word on whether the girl was being watched by an adult at the time of the tragedy.
