Two more set fires in the last two days on Columbus' South Side have inspectors looking for new crime clues.
A twelve year old boy charged earlier with several South Side arsons escaped from a juvenile lock-up in late March.
Battalion Chief Dave Whiting says fire investigators want to talk further with the youngster.
"He's going to be a person of interest, obviously, because he was charged with arson already and he escaped, and I know there is an arrest warrant out for him," said Chief Whiting.
Since early January at least a dozen fires have plagued South Side neighborhoods.
