Dennis Mejia is a con artist claiming to be Javi's paternal uncle from Honduras. While posing as the uncle, he attempted to blackmail Joe Cruz into giving him a check for $50,000 in exchange he doesn't pursue full custody. Unfortunately, upon learning from Brooke Katz that Dennis was claiming to be the brother of Javi's father, Joe pointed out that there was no father named in Javi's birth certificate so Joe and the Chicago Police Department set up a sting to get Mejia in the act. Dennis took the bait and was arrested for fraud.
