Investigation Continues

FORT RECOVERY — Investigators say they have made some progress in the double homicide of a father and daughter last month in Fort Recovery.

In a news release, Mercer County Sheriff Jeff Grey said deputies and agents with the Ohio Bureau of Criminal Identification and Investigation from the Ohio Attorney General's Office Special Investigation Unit continue to comb evidence in the murders of Robert and Colleen Grube. The father and daughter were found bound and murdered on Nov. 30 in rural Fort Recovery.

Grey said investigators have made “major progress” in the case. Officials have narrowed down the time of the incident to a two-hour window. It also appears several suspects, including a male and a female, could have been present at the scene of the crime. Grey said he is still asking for the public’s help to report any suspicious activity on Nov. 29 and 30.

“While we still don’t know who committed this terrible crime, we have collected volumes of evidence that I believe will eventually lead us to the killers,” Grey said. “This case will not result in an arrest quickly, but I am confident that the case will be solved.”

Officials have previously said a Toshiba laptop was taken from the Grube home. Grey also noted there were no signs of forced entry.

During the course of the investigation, officials have conducted more than 70 interviews, followed up on 60 tips, asked for 46 court orders and subpoenas and obtained 11 search warrants.
