SOUTH JORDAN, Utah -- South Jordan Police are searching for a missing girl Thursday.
Police said 6-year-old Kassidy Nelson was last seen at her home in South Jordan around 9:30 p.m. Wednesday.
Officers said they want to talk to the girl's biological mother, Megan Boynton, and her boyfriend, Elliot Proctor. Police are calling them persons of interest.
Kassidy's legal guardians are her great-grandparents. On Tuesday, they said they argued with Boynton regarding custody and visitation. Kassidy's great-grandfather told police he heard Kassidy unlock the deadbolt on the front door Wednesday, but she was gone by the time he got there.
Although police have issues an endangered missing child alert, they believe Kassidy is not in immediate danger. She has a good relationship with her mother, and police would like to get in touch with Boynton because she does not have legal custody.
Kassidy was last seen wearing a multicolored striped fleece jacket, a yellow, bumblebee shirt, black pajama pants and no shoes.
Boynton and Proctor were last seen driving a dark colored Chevrolet Silverado. Boynton has brown hair, blue eyes, is five foot three inches, and about 130 pounds. Proctor is six feet 1 inch, 185 pounds with brown hair and blue eyes.
The couple do not have a current address, which is making it more difficult for police to locate them.
Anyone with information is asked to contact the South Jordan Police at (801) 840-4000.
