The Murder of Ariel Sellers

Ariel Sellers lived in Hawaii with her biological parents, Melanie Joseph and Adam Sellers, along with her three siblings. In 2019, Ariel and her siblings were removed from their home by Hawaii Child Welfare Services. Family Court later terminated her biological parents' parental rights and all four children entered the foster care system.

Ariel was placed with Isaac Kalua III (known as Sonny) and Lehua Kalua in Waimanalo, Hawaii. During the foster placement period between 2019 and January 2021, records later reviewed by journalists documented multiple bone fractures, bruising, noticeable weight loss, and developmental and behavioral concerns. Court explanations presented at the time suggested possible medical or developmental conditions to account for some of the injuries. Despite these documented concerns, the placement continued and adoption proceedings moved forward.

In January 2021, Ariel was officially adopted by Isaac and Lehua Kalua. Her name was legally changed to Isabella Kalua. She was six years old.

Investigators later alleged Ariel had been killed weeks before she was reported missing, in mid-August 2021. A sibling statement referenced in court documents described witnessing abuse inside the home. One of the children told investigators that Ariel was placed inside a dog cage and that duct tape had been placed over her mouth and nose. The child stated that Ariel did not wake up. Her body was allegedly concealed and disposed of. Her remains have never been recovered.
