The mother of an Oregon teenager who drowned after a swim practice in 2019 has filed a $70 million wrongful death lawsuit.

Nabila Maazouz, a 14-year-old freshman at Oregon Episcopal School and member of the Liberty High School swim team, was found dead under a pool cover at Hillsboro’s Shute Park Aquatic & Recreation Center after a team practice on Nov. 20, 2019. 

According to the Oreogonian, the lawsuit alleges that coaches instructed swimmers to cover the pool with heavy covers that create suction when rolled onto the water. Several swimmers who participated in this routine noticed Maazouz’s disappearance, which allegedly took place while the pool was being covered.

Nabila’s mother Patricia Maazouz was waiting in the parking lot as team members exited the facility without her daughter. After going back inside to search the property with coaches, Maazouz found her daughter unresponsive under the covers in the deep end of the pool.

The city of Hillsboro, the school district, and the city’s Parks and Recreation Department are among those being sued by Patricia Maazouz for wrongful death and negligence. The lawsuit claims the design of the ThermGard pool covers was “unreasonably dangerous,” which allowed Maazouz to become trapped underneath. ThermaGard’s manufacturer Universal Filtration Inc., as well as its seller the Pool and Spa House, are named as defendants in the lawsuit.
