7 mysteries from the 'execution-style' deaths of 8 relatives in Ohio

1. What clues at the scenes led investigators to determine these were planned, sophisticated, “execution-style” killings?

The dead included seven adults and one 16-year-old male, most of whom were executed while in bed. All appeared to be shot in the head "execution-style," Ohio Attorney General Mike DeWine said.

"This is a pre-planned execution of eight individuals. It was a sophisticated operation and those who carried it out were trying to do everything they could do to hinder the investigation and their prosecution," DeWine said. "We don’t know if it was one or two (shooters)."

Autopsy results are expected to be released Tuesday or Wednesday.

"This investigation is very large, probably the largest in Pike County we have ever been a part of," Pike County Sheriff Charles Reader said.

Reader said he suspected the killings were targeted and none of the victims appeared to have committed suicide. All the killings occurred during the nighttime hours.

According to Wikipedia, an execution-style murder — also known as Chicago-style murder and execution-style killing — is an act of criminal murder where the perpetrator kills at close range a conscious victim who is under the complete physical control of the assailant and who has been left with no course of resistance or escape. Oftentimes, the victim is put on his or her knees.

2. How did authorities determine marijuana grow operations found at the scenes were for professional, and not personal, use?

DeWine said marijuana grow operations were found at three of the four crime scenes, but he did not disclose the amount of drugs found.

Authorities also wouldn’t say publicly whether they thought the killings were drug-related, but an official with knowledge of the operation told CNN’s Nick Valencia: "This operation was not for personal use; it was for something much bigger than that. It was a very sophisticated operation."

"We have received over 100 tips, we have conducted over 50 to 60 interviews … over 100 personnel were involved in this investigation. Five search warrants have been executed, four crime scenes have been worked," DeWine said.

Also, 18 pieces of evidence are at the Bureau of Criminal Investigation’s state crime lab.

3. Why were the children spared by the killers? Where are the children now?

In all, three children — a 4-day-old, a 6-month-old and a 3-year-old — were found unharmed at the scenes, officials said.

It is unclear at this time why the children were spared. State authorities are reportedly caring for the children.

4. Who are the Rhodens?

The identities of the eight people killed are: Hannah Gilley, 20; Christopher Rhoden Sr., 40; Christopher Rhoden Jr., 16; Clarence “Frankie” Rhoden, 20; Dana Rhoden, 37; Gary Rhoden, 38; Hanna Rhoden, 19; and Kenneth Rhoden, 44.

The Rhoden family is a large family spread across several counties in southern Ohio.

Both Christopher Rhoden Jr. and another victim, Frankie Rhoden, worked at Big Bear Lake Family Resort, according to social media posts. Two of the victims, Frankie Rhoden and Hannah Gilley, were engaged, according to the "Remembering Frankie Rhoden" Facebook page.

Reader said the family did not have prior criminal contact with his office.

At a press conference Sunday, Reader said he warned other Rhoden family members to be on guard, but "for other citizens, I don’t believe there’s an issue."

A relative of the Rhodens, who didn’t want to give his name because he fears for his safety, described the slain family as "good people, good hard-working people … never bothered nobody. Takes a cold-hearted person to do something like that and hopefully they’ll be brought to justice as soon as possible."

5. What is the profile of the perpetrator(s)?

No suspect or suspects have been apprehended.

While survivors of the family are asking for the public's help in finding those responsible and investigators continue to seek answers, no details about the perpetrator's or perpetrators' profiles have been released by authorities.

Authorities said at least one suspect is believed to be at large and should be considered armed and dangerous. Investigators also said the killings were "planned and sophisticated."

6. How did the killer(s) gain entry into the homes in the middle of the night?

Details of how the killer or killers gained entry into the family's homes have not been released to the public but we are working to obtain more details from the investigation through public records requests.

Seven of the deceased were found in three Union Hill Road homes in Piketon. The eighth was found within a 10-minute drive from the other victims.

Two recordings of the first 911 calls that Piketon police received Friday were released.

The first call came from a woman named Bobby at 7:49 a.m. Friday. She told dispatchers she'd come to feed animals and used a key to gain entry into the house in the 4000 block of Union Hill Road and "found them all dead."

The home is where two males were found dead — her brother-in-law Chris Rhoden and cousin Gary Rhoden. The woman said in the 911 call there was "blood all over the house" and someone "beat the hell out of them." The men were found lying on the floor in the back bedrooms.

She reported that no one else was in the home and broke into tears, according to the 911 recording.

A man is heard in the second 911 call, recorded at 1:26 p.m. Friday.

The man was at a residence in the 700 block of West Fork Road. He told the dispatcher he walked in and called out for his cousin before finding him dead with a gunshot wound.

The news of the other deaths had already been reported by the time this death was discovered.

“All that stuff that’s on the news, I just found my cousin with a gunshot wound,” the caller tells the dispatcher.

7. Is there a history of drug problems in Pike County?

In August 2012, Ohio law enforcement officers found "a major marijuana grow site in Pike County with suspected ties to a Mexican drug cartel," according to a press release DeWine's office issued at that time.

Investigators discovered about 1,200 marijuana plants — which were destroyed — and evidence of two abandoned campsites they believe belonged to Mexican nationals.

It has not been indicated by authorities that there is any connection between te incident in 2012 and the operations found on the Rhoden properties.

Piketon is a community of 2,158 in Pike County, which has 28,217 residents, according to the 2015 census. The county is classified by the Appalachian Regional Commission as "distressed" and the unemployment rate is among the highest in the state, according to the county website.

Community members said news that investigators found marijuana growing operations at three of the four crime scenes is not entirely surprising.

"I'll tell you, the drug scene in this area is just so bad that you never can tell," said Chip Moore of Piketon.

"That’s Pike County. … It’s one of those things that's everywhere, really," said Surienna Nye of Piketon.
