You are right. Zeke may not be here.
However, the little boy was not the only one who saw grandma's dog "Tahoe". There is another witness, very reputable, who saw the same dog, saw the flier and thought it was Zeke. Given that this dog arrived for the first time at the time Zeke went missing, there is reason to believe that there may be a connection.
I don't think anything will happen unless a positive ID is made tho. |
