"The parties have resolved the case without the need for further involvement of the court," Naudin said. "As this is a matter involving minors, we are pleased that the situation has been dealt with in a reasonable manner, despite having to file the lawsuit."
The video was done in May while the three girls, who attended Riverwood Middle School, were off campus. The lawyer father of the girl allegedly targeted in the Facebook posting gave the video to school officials, plus sent cease-and-desist demands to the families.
For its part, Facebook removed the video in accordance with its abuse policies.
The defamation of character lawsuit was filed in June. All three girls denied the allegations.
Names of the children haven't been made public, but all of the children live in Kingwood and are students at Riverwood Middle School in Humble ISD.
