The Ohio Attorney General’s Office will be devoting more resources to helping solve cold case homicides across the state, offering services from the Bureau of Criminal Investigation to local police agencies.

“This is ultimately an effort to help law enforcement and victims,” said Attorney General Mike DeWine. “Currently, the oldest cold case homicide on the Attorney General’s website dates back to 1964. We hope to bring closure and justice to as many cases as possible so that victims and their families can have justice.”

Also under the new effort, every Ohio cold case homicide will be also be listed on the Attorney General’s Unsolved Homicides website, which listed 166 cases last week, including eight posted by the Clark County Sheriff’s Office, plus cases listed by area police departments such as Beavercreek, Miami Twp., West Chester and Sugarcreek Twp. According to FBI statistics, Ohio has 5,153 unsolved homicide cases.

Listing a cold case is voluntary for police departments, but DeWine said he hoped more would post information about cold cases there.

Last week, DeWine’s office started integrating information from Dayton’s cold case website, found at www.daytonohiopolice.com/coldcase/, into DeWine’s, said Dayton Det. Patricia Tackett, who oversees cold cases.

DeWine made the announcement last week from Mercer County, where the sheriff is still investigating the Nov. 30, 2011 homicides of Robert Grube, 70, and his daughter Colleen, 47. Both had been bound with duct tabe and shot, and their bodies were found in their house.

The Grubes were one of four cases that NewsCenter 7 focused on for Miami Valley Murder Mysteries, a Sept. 13 special about cold cases.

“This, by far, is the worst homicide case I’ve seen in my 32-year law enforcement career,” said Sheriff Jeff Grey, who also announced that the Grube reward had been doubled, from $10,000 to $20,000. “I appluad the Attorney General’s effort to draw more attention to, not only this case, but also to other unsolved homicides around Ohio.”

DeWine said that BCI experts would be available to help local departments with cold cases in the following ways:

— The Special Investigations Unit can review cases, assist with interviews, and provide follow-up support.

— The Crime Scene Unit can identify evidence for submission to lab.

— The Crime Laboratory can analyze evidence that has been properly preserved.

— The Criminal Intelligence Unit can digitize and preserve case files.

— The Cyber Crimes Unit can examine electronic devices like phones.

DeWine said the office will also feature one Ohio Unsolved Homicide case each month, hoping to draw more public attention. People with information about the cases will be asked to call the BCI tip line: 855-BCI-OHIO or 855-224-6446.
