Was there bank robbers named Rita and Moe Selig?

They aren't real just made up characters in the movie. As said in Beethoven's 5th movie, they were like Bonnie and Clyde only Moe and Rita Selig said please before they robbed the bank and then Moe left a red carnation. Only Bonnie and Clyde didn't say please before they robbed a bank or leave a red carnation behind.
