Ohio Attorney General Mike DeWine announced on Monday that a comparison of Ariel Castro's DNA to the nationwide pool of DNA profiles returned no matches.
The FBI ran the nationwide Combined DNA Index System (CODIS) search this morning, comparing the suspect's DNA to every DNA sample previously submitted to the system.
Last week, forensic scientists with the Attorney General's Bureau of Criminal Investigation (BCI) compared Castro's DNA against all DNA submissions statewide, also returning no results.
DNA samples from the suspect's brothers, Pedro Castro and Onil Castro, were also tested and compared to the state and national CODIS submissions. No matches were returned.
