Let's just say I have been following the case for a while and have some context that is missing on the article. She "filed a petition for release", on the same way you file for a fishing license if you write "help me" on every field and mailing it over to the overseeing body.

As per the same article

The one-page petition doesn’t include any arguments for Geyser’s release. Instead, it cites state laws that require Bohren within 20 days to appoint at least one expert to examine her and produce a report within 30 days of being appointed. The petition also requests the judge schedule a hearing, noting that state law requires him to hold one within 30 days of receiving the examiner’s report. Bohren set the hearing for Nov. 1.

Schizophrenics with enough understanding of their condition can be released to the society, provided they keep getting help. Picture yourself a believer in a god, and if said deity appeared to you, beyond any shade of a doubt and commanded you to kill one person to save the world, Would you do it?

Schizophrenia not only gives you delusions, it also influences you to believe they are real, and many people afflicted by such condition have gotten better through treatment and medication.

I might be reading the article with kinder, hopeful eyes, because I have worked with people suffering from that condition for a very long time, but to me, it looks like she is now, aware of what she did and reaching out for help.
