COLUMBUS, Ohio (AP) -- Attorney General Mike DeWine says the number of cold cases listed in an Ohio database of unsolved homicides has more than quadrupled since September.

The online database had fewer than 170 cases in September when DeWine asked law enforcement agencies to submit their cold cases. Now the database includes more than 1,000 cases, and expected submissions from Cleveland police and the Montgomery County sheriff in Dayton could double that size.

DeWine says tips have come in on some cases, and the hope is that the tips lead to arrests.

In all, more than 50 law enforcement agencies submitted at least some of their cold cases for the voluntary database. It includes 423 cases from Cincinnati police and 376 from Dayton police.
