Authorities in Ohio say four family members arrested in the 2016 shootings of eight people carefully planned the killing for months.

Ohio Attorney General Mike DeWine announced Tuesday that a grand jury indicted the four on aggravated murder charges and that each of them could be sentenced to death if convicted.

DeWine says he can't release many details about the motive but he did say the custody of young child played a role.

Authorities took into custody four members of the Wagner family who had lived in southern Ohio, but moved to Alaska after the killings.

A lawyer representing the family says they will be vindicated.

DeWine says the Wagner family knew the victims well and spent months studying their routines and the layouts of their homes.

A lawyer representing a family arrested for the killings of eight people in Ohio says the family will be vindicated.

Attorney John Clark represents the Wagner family who were arrested Tuesday for the 2016 killing of eight members of the Rhoden family in southern Ohio.

Clark says family members look forward to their day in court so they can clear their names.

Clark says in a statement the family is waiting for the day "when the true culprits will be discovered and brought to justice for this terrible tragedy."

Clark has previously said Wagner family members provided laptops, phones and DNA samples to investigators, and agreed to be interviewed about the slayings.

The Wagners lived in Peebles in southern Ohio at the time of the killings but later moved to Alaska.

Authorities say a family of four has been arrested in the slayings of eight members of another family in rural Ohio two years ago.

The Ohio Attorney General's Office announced the arrest Tuesday of four members of a family who lived near the scenes of the killing.

No motive was announced.

Those arrested are: 47-year-old George "Billy" Wagner III; his wife, 48-year-old Angela Wagner; and their sons, 27-year-old George Wagner and 26-year-old Edward Wagner. The Wagners had since moved to Alaska.

A message was left with a lawyer who has been representing the Wagners in the investigation. An attorney has said previously the family cooperated with investigators.

The arrests are the culmination of a massive investigative effort since seven adults and 16-year-old boy were found dead in 2016 at four homes near Piketon.
