After calling the police, they said that work on the retaining wall had begun (since he tore it down). They also said that he had technically 'started to refinish the pool deck as evidenced by the large gray primer spot.'
I argue that painting a 20 sq ft patch of primer is a far cry from starting the work- but legally it is apparently sufficient that the Rockwall police department had no interest in even investigating my claims of criminal theft.
I decided that I can remain embittered toward Mr. Garcia (which I confess I still struggle to forgive a man who has no remorse for his actions and continues to defraud others) *or* I can pray that God would help me find personal forgiveness against him while allowing Him [God] to balance the ledger at the final judgment.
I ultimately completed the painting and privacy wall myself. I paid a different trustworthy contractor $3200 to complete the retaining wall and had to dispose of all the debris myself. The gray primer spots and spilled paint remain to this day a reminder of my lack of thorough advance examination of the character and reputation of Mr. Garcia.
Beyond that, I will only occasionally post updates, not out of an obsession with ruining Mr. Garcia but to keep the posts timely so they remain at the top of Google searches that others may be warned before signing a contract with Juan Garcia III dba Garcia Construction Company.
