Following his arrest for allegedly killing his mom and dad, a criminal complaint detailing the gruesome case claimed Gordon Lasley Jr. murdered his parents with a machete, WHO-TV reported.
Lasley, 25, was charged with two counts of first-degree murder for the death of his mother, Kim Lasley, and father, Gordon Lasley Sr. Their bodies were discovered by their second son, Tyler Lasley, on Wednesday night in their home on the Meskwaki Tribal Settlement in Iowa.
According to the complaint, Gordon Lasley Jr. admitted to other family members that he killed his parents with a machete. When law enforcement officials found him, he was driving his mother's car, with blood on his clothes and inside the vehicle. He also had visible cuts on his hand.
The machete, covered in blood, was found in the living room.
Officers from Meskwaki Nation Police were originally called on Wednesday night after reports of a possible homicide. Once the investigation began, they were joined by Iowa Department of Criminal Investigation, Tama County Sheriff's Office, Tama police department, Toledo police, and the FBI.
According to FBI spokeswoman Sandy Breault, the FBI is assisting in the case since the agency usually becomes involved in serious crimes that occur on Indian land.
On Thursday, Assistant U.S. Attorney Pete Deegan would only say that the incident is being investigation by state and federal authorities. He did not disclose whose jurisdiction the case would fall under.
He is currently being held in Tama County Jail on $2 million bond. A preliminary hearing is set for Feb. 14.
"The Sac and Fox Tribe is a very close community and we are all shocked and saddened by this," said Judith Bender, tribal chairwoman, in a statement. "Our thoughts and prayers go out to the family and all of those who are affected by this horrific event."
