Grey: Progress Continues In Cases

CELINA — A year after a double homicide rocked a rural Mercer County town, Sheriff Jeff Grey says investigators are continuing to make progress in the case.

On Nov. 30, 2011, Robert and Colleen Grube were found duct taped and shot to death in their rural Fort Recovery home. There were no signs of forced entry into the home.  The investigation into the deaths of the father and daughter has included hundreds of interviews and a review of scores of pieces of evidence. Members of the Ohio Attorney General's Office also are assisting in the case.

"We have a detective who is working this case pretty much full-time," Grey said during a news conference Thursday morning. "We've also received a lot of assistance from other law enforcement agencies."

The Darke County Sheriff's Office and the Randolph (Ind.) County and Jay (Ind.) County sheriff's offices have provided assistance in the case. Grey said those agencies have gathered a lot of evidence and worked closely with Mercer County investigators on the case.

"Detectives have also traveled throughout southern Ohio," Grey said. "We spent a lot of time in southwestern Ohio, we've been to Indiana, we've been to Kentucky, we've been to Tennessee and we've been in contact with law enforcement agencies in other states as we investigate this crime."

Evidence continues to roll into detectives working the case. Some evidence has surfaced as recently as the past few weeks.

"We are still continuing to submit more evidence to the lab," Grey said. "The information coming in has slowed down, but it's still coming in."

Investigators have ruled out a number of people as potential suspects in the homicides. Grey said investigators continue to follow up on leads regarding possible suspects as well.

"We have some individuals that I'm not comfortable calling suspects quite yet at this point, but we are very curious about them and that is our focus at this point," Grey said. "We are really focusing and putting a lot of effort into a few people that we believe might possibly be involved in. There's a good indication we might be on the right track. Hopefully, we'll have some resolution soon."

A $20,000 reward has been posted for information leading to the arrest of those responsible for the homicides. Grey also updated media on the search for Daniel Charles Martin. Martin, 40, has an arrest warrant for murder in connection to the shooting death of Melinda Shinn on Nov. 8 in Rockford. Hours after the shooting, Martin's red Ford Explorer was located in Fort Wayne, Ind.

"Our detectives are working very closely with other law enforcement agencies, both in Ohio and outside Ohio, attempting to locate him," Grey said. "Right after the warrant was issued, we requested the assistance of the United States Marshals Service. They have a lot more resources, a lot more tools. They are very professional in tracking people down."

The marshals service posted a $2,500 reward for information leading to Martin's arrest. Grey also encouraged anyone with information to contact the sheriff's office.

"If someone sees him out on the street or knows where he is at, they should contact their local law enforcement agency immediately," Grey said. "He has been entered with a nationwide pickup ... We do believe he is still armed."

Grey did not field questions from the media at the news conference.

While 12 months have lapsed without an arrest in the Grube case, Grey assured residents work continues on the case.

"This is not a case that is sitting on the shelf," Grey said. "It's a case we are very active in working and putting a lot of resources into. It could take us some time yet, but I believe we are going down the right path."
