Police has classified the girls as being ‘critically endangered’ and have leads on a campsite. This may be another Christopher Watts situation.
Sisters Paityn, nine, Evelyn, eight, and Olivia Decker, five, vanished on Friday after their father, Travis Decker, 32, collected them from their mother's house for a scheduled visit.
Since then he has gone AWOL, sparking a massive police hunt and fears for the girls' safety.
His ex-wife, the girls' mother, is particularly worried because he has 'really struggled since he left the military'.
'His mental health can be hard sometimes,' she told KIRO 7.
The girls were last seen around 5pm on Friday when they left their home with Decker.
