Neighbor's house has squatters

[Kristy Borwegen]

Hello!  New here... I recently purchased my house, and have noticed that it looks like squatters are living in my neighbors house.  I went on the county website but the only info for the potential owner is the property next door.  I can see that they have not paid their taxes, but Im stuck as to what else I can do to try to contact them.  Also, what is the usual time frame for properties to go to tax auction?  Thank you in advance for any help.
