First-degree murder indictment along with charges of conspiracy were filed against Chad Daybell and his wife Lori Vallow over the deaths of the latter’s two children in Idaho, according to prosecutors on Tuesday.

Their victims were named Joshua or J.J. Vallow and Tylee Ryan.

Apart from these charges, Daybell also faces murder charges for the death of his. He is also indicted for insurance fraud, Fremont County prosecutor Lindsey Blake and Madison County prosecutor Rob Wood said in a combined press statement.

“Fremont Prosecutor Lindsey Blake and I believe all three homicides and the related financial crimes were committed as part of a continuing criminal scheme,” said. “The unprecedented cooperation among law enforcement has been a model of cooperation, diligence and commitment. Every person who has worked on this case is to be commended for their diligence and steadfast pursuit of justice for Tammy, Tylee and JJ.”

“Local, state and federal law enforcement professionals and local and state prosecutors have worked tirelessly for nearly a year and a half to gather the facts and evidence necessary to bring forward charges on behalf of Tylee, JJ and Tammy,” Blake, meanwhile, stated. “Due to the ongoing safety restrictions imposed by the courts during the pandemic, we just recently were given permission to present information to the Grand Jury for their review. They deliberated and determined there is probable cause to believe that the Daybells willfully and knowingly conspired to commit several crimes that led to the death of three innocent people.”

Furthermore, Vallow was accused of Grand Theft in relation to the benefits from Social Security Survivor worth $1, 000. The amount was supposed to be used for the care of the two suspects and “were appropriated after the children were missing and ultimately found deceased,” prosecutors said.

The two suspects were not able to answer PEOPLE when they were reached for a comment.

The two kids, aged 7 and 16, have disappeared and were found in Daybell’s property.
