What's the Statute of Limitations on Physical/Emotional Child Abuse

[Bakes]

Hello. I live in Oregon, and I'm trying to help out a friend of mine who wants to get away from her abusive family. Here's basically what's happened:

When she was 8, she was continually molested by her half-brother, who was 17 at the time. She told her mother about it, and was taken to a counselor. But they moved to Louisiana before anything could be done, and the mother seemed to just forget about it, so she didn't go to counseling anymore. The half-brother stayed with them, and didn't leave until he turned 21.
Up until she was about 10, her father abused her physically, and continues to abuse her mentally. Her mother does the same, calling her useless, worthless, and "kicking her out", then calling the cops on her when she leaves.
They have also been abusive to her older siblings, such as the father hitting her half-sister in the face and breaking her nose. The mother did nothing about this, either.
Her mother also denies her medical attention. For a full week she put off making my friend's follow up doctor's appointment on the side effects of medication she was taking (she also needed refills).
We told the principal and counselor at our school, and when the mother denied the accusations, they told me and my mother that we probably had "bad information", not considering the possiblity that, gee, the mother might be lying.

My friend is 14 now, and is very desperate to leave. She's considering everything from emancipation to telling lies that would get her thrown out for good. She's staying with me for the weekend and we're trying to figure out what can be done.

Did you read the emancipation sticky?

Then you already know that, at 14, emancipation isn't an option.

Have her call Child Protective Services about the abuse.

One last thing... 14 year old kids have a tendency toward the dramatic. The CPS folks will need evidence.

How do you provide evidence of emotional abuse, though? Would a recording work? The only thing I worry about in that case is people assuming it was just one nasty fight. Although she has other friends that can vouch for her as well...
