Can an adult sibling get custody of their minor sister if her father is both mentally and physically abusive towards her?

Question Details:

My 13 year old sister lives in CO with my father. She is being verbally and mentally abused (as he did with all of his children). She ran away from home but he found her. She has 5 adult siblings in CA that would all love to take care of her, plus her maternal grandparents are there also. Is verbal and mental abuse of a minor taken seriously in court? She called me the other day when she ran away and said she wishes she was dead with her mother, and that she hates my father and can't take it anymore. What, if anything, can I do? Important Notice
