One worth Euthanising

This bottomfeeder is harassing my sister, trying to extort money out
of her for a 18 y.o. judgement that was supposed to be paid by her ex.
He can't find her so he is making her life miserable.

This guy operates a compnany called Loan Resource Mgmt out of his
house. His name is John Cottrell of Loan Resources Management, Inc.
and he lives at 6409 Parkmont Drive, Arlington, Texas 76001 and his
wife's name is Christine.  He lives in Tarrant County.

Thanks for any help.
