Contacting homeowner via Facebook to make offer

[Elex Price]

I recently found this vacant property in my hometown back in Mississippi. I would like to purchase the property. I looked on the Hinds County website and found the name of the owner. Looks like it was deeded via an Estate. I did a google search on the owners name and came across his Facebook profile. 

My question is has anyone contacted a home owner via Facebook before? Or would you recommend contacting this owner via Facebook to ask if interested in selling their property?
