LOWER TOWNSHIP — The parents of a toddler who died after falling into a campground septic tank the night before Easter are suing, saying that the lid was unsecured. Scott and Ashley Davidson, of the Delmont section of Maurice River, say in their lawsuit that their 3-year-old daughter's deadly slip was not the only time that septic tank lids at the facility were found to be left dangerously loose. An unresponsive Emma Davidson was pulled from a sewage septic tank at Sun Outdoors Cape May around 9:30 p.m., according to the Cape May Prosecutor’s Office. She died shortly after at a local hospital.
