Benton County Coroner John Hansens hopes to release his final report Oct. 10 on the June 9 deaths of two Kennewick children.
The coroner’s report will contain both the cause and the manner of death for Kaitlin and Ethan Austin, Hansens said.
The siblings were found shot in their Hansen Park home. Kaitlin, 16, was shot several times and Ethan, 12, died of one gunshot wound to his head.
Kennewick police previously have said no one else was involved in the deaths.
Never miss a local story.
In August, Hansens said toxicology reports showed that neither had drugs or alcohol in their system when they died.
Hansens said Thursday that the coroner’s report and a news release are being reviewed by the Kennewick Police Department and Benton County Prosecutor’s Office before he can send out the information.
