PORTLAND, Ore. — The estate of a 15-year-old girl who died while under the watch of child-welfare workers has filed a $9.5 million lawsuit against the state of Oregon.

The Oregonian/OregonLive reports (http://bit.ly/2gzEhxe ) the estate of Gloria Joya filed the suit on Thursday, claiming the gastrointestinal issues that she died of in April 2016 weren’t properly treated.

The suit claims child-welfare workers failed to intervene in the girl’s life despite being contacted 28 times with concerns about Gloria’s health and safety.

The lawsuit claims the state Department of Human Services didn’t remove Gloria from her mother’s custody until about a year before the girl’s death — years after the first signs of stress-related gastrointestinal problems surfaced and shortly after the girl had contemplated suicide.

Department spokeswoman Andrea Cantu-Schomus declined to comment.
