Prosecutors say the sex assaults had been happening for several months before Phelps’ fiancĂ©e found emails describing them on April 8.

Authorities say Phelps had known the victim’s father for years and has known the victim since she was born.

Authorities say the girl told police the sexual contact began when she was 11 years old or younger. Police say she told them her and Phelps began having sex when she was 14.
