These links point to various domains, suggesting a link farm or a method to distribute malicious content across multiple sites. The primary URL found in the document body is http://policetrailer.com/uploads/1/3/0/6/130603861/130603861.html#no+oyes+ladrar+los+perros+analisis+l, which is also part of this link farm.
