How to get in contact with owner of abandoned home

[Emond Hobbs]

Hello BP community, I found a house in a great neighborhood that looks to be abandoned due to the overgrown landscaping and no furniture in the house. I looked up the property on my county website and was able to get the homeowners name and old phone number. I tried calling the number several time but it is no longer active. I also tried finding the owner or any relative's on social media but have not been able to find anything. If anyone has any advice on where I should go from here it will be greatly appreciated.
