A teenager died after saving her younger siblings from drowning and was unable to save herself. Vaverlyn Dachbar, from Phoenix, Arizona, was on a family trip to Lake Pleasant on Friday when the tragedy took place.

Her twin brother and sister were out swimming and went under after they waded in too deep. Vaverlyn, who is said to be only an average swimmer, jumped in and managed to save them, but was unable to save herself. A Maricopa County Sheriff’s dive team found her body later in the day.

Vaverlyn was a sophomore at Thunderbird High School. Her family says she was an avid reader who was already taking extra classes to graduate early. Her dream was to be a pediatrician one day.
