The wife of a lacrosse coach, who was also considered the "team mom," is accused of raping an 11-year-old team member, Pierce County prosecutors say.
Su Dillon, 44, was charged Wednesday with four counts of first-degree rape of a child.
Investigators said Dillon allegedly had sex with the boy between May 20, 2014 and May 19, 2015.
The investigation started April 5, when police received a call from the victim's mother.
According to probable cause documents, the mother reported that her son, who was on the lacrosse team, had been having sex with Dillon since he was 11 years old.
The mother reported that her son had been acting out the last couple years and she had sent him to live with his father in Virginia.
While in Virginia, the boy showed signs of improvement and according to court documents, during counseling, the boy disclosed having sex with Dillon.

According to probable cause documents, the boy told investigators that it started when she allegedly kissed him on the lips when he was 10 years old at her house, where he said he would spend time at her home and that she was the mother of one of the team members.
Investigators said the boy reported that they had sex four times: twice at Dillon's home, once at his house and once during a lacrosse trip in San Diego.
“He said the kiss was on the lips when he was 10”, according to the court documents.
“He said one time on a ride home she pulled over and told him that what they were doing was a secret because she wanted their relationship to continue and become more serious”, and that “the first time they had sex he was spending the night at her house”.
On April 30, Dillon denied the allegations as she was interviewed by investigators and said she was not the "team mom," but would help out the team.
In court documents investigators said Dillon at first told them the boy had initiated the relationship. “But an 11 year old cannot initiate sexual contact with a female adult,” said Pierce County Sheriff’s spokesman detective Ed Troyer. “The female adult has all the culpability here.”
Dillon later admitted to having sex with the victim, court documents said. She said that she "was the adult and should have known better." She also admitted "having problems in her marriage and that the victim made her feel good."
According to probable cause documents, Dillon said she knew it was wrong and wanted to end the relationship. She also denied that this happened with any other boys.
Investigators say because Dillon had access to other kids on the lacrosse team there is concern there are other victims who have not come forward.
“So what we need to find out now is if there are other victims out there,” said Troyer.
Dillon pleaded not guilty to four counts of child rape and was released from the Pierce County Jail without bail while she awaits trial.
