Wa State: What Are The Obligations To Protect Family From Suicide

My sister has been in and out (escaping) of hospitals for suicide attempts for the last nine months. She is currently under supervision at either my home and our parents home after we recently found her in the middle of Oregon trying to get to a beach to drown herself (eloped from a hospital in Seattle). She presents with extreme frequent panic attacks, frequent escaping and attempting to escape our supervision. She never wants to see another therapist and frankly her many therapists have yielded no results. She frequently begs us to let her go so she can die.

Her plan is to get away and not tell anyone where she is and drown herself. So far we’ve been able to find her every time, all doors at our parents are alarmed, there are many of us. We are doing everything we can but she is desperate and not responding to any help, talking, or safety plans.

Are we obligated to send her to a locked hospital? A plan she keeps saying is she will not sign a hospital ROI, fake screening results, and escape with no one the wiser: she’s already escaped this way twice. She says if we send her to the hospital it will be the last time we see her.

Are we obligated to keep her locked somewhere? Are we obligated to always have someone on her tail? Can we use force to keep her from escaping? Are we even justified to do these things?? She is BEGging for death. Constantly.

NO ONE wants her dead. She is so so so precious to SO many people, SO many are praying, she has loved ones crying themselves to sleep every night. We have multiple other family members who manage suicidal ideations, some of us are terrified of a domino effect. She is my closest sister.

Are we justified if she escapes (from home or a hospital) and does it when we KNOW her plan? I caved and googled Assisted Suicide and threw my phone across the room. Every question seems so trivial! This is my sister’s life!
