HARPSWELL — Officials say that a 75-year-old woman and her dog have died after they were struck by a car in Harpswell.

The Cumberland County Sherriff’s Office said that Rita Douglas was walking her dog on Harpswell Islands Road on Wednesday when she was struck by a pickup truck. The office said both Douglas and her dog were killed on impact.

Officials say the driver was 16-year-old Isabella Slocum, who is also from Harpswell.

Rita Douglas’ husband, Robert Douglas, told The Portland Press Herald that the two were planning to celebrate their 49th wedding anniversary on Sunday. Robert Douglas said his wife was born in Germany and they met while he was stationed there with the military.
