According to newly released court documents, Oklahoma investigators have found a trove of evidence against numerous defendants charged with murders of Veronica Butler and Jilian Kelley.

“These people are idiots. They left a trail a mile wide,” Nancy Grace said during Thursday’s “Crime Stories.”

As CrimeOnline previously reported, Tifany Adams, 54; Tad Cullum, 43; Cole Twombly, 50; and Cora Twombly, 44, have been charged with two counts of murder, two counts of kidnapping, and conspiracy in the deaths of  Butler, 27, and Kelley, 39, on March 30.

Police later arrested 31-year-old Paul Grice on the same charges.

Court documents stated that warrants allowed investigators to dig at a cow pasture leased by Cullum, connected to the suspects by cell phone data. Following two days of digging, investigators found a chest freezer containing the bodies of Butler and Kelley.

“So they dug 15 feet, they found this incredibly large ice chest freezer. they call it a trunk, if you will,” Investigative Journalist Lauren Conlin told Grace. “And unfortunately, they found Veronica and Jillian.”

According to court documents, other items found in the trunk included jeans, sweatshirts, t-shirts, a black jacket, cloth gloves, ball caps, duct tape, and a sheathed knife.

Investigators also found, in part, a .380 ACP Taurus handgun with a full magazine, one live round in the chamber, kitty litter used for absorption, trace DNA evidence, and digital evidence inside a truck belonging to Cora and Cole Twombly.

Documents also revealed that Cora Twombly’s daughter was instructed to clean the truck’s interior after Cora and Cole returned from their “mission.” The daughter’s friend also helped clean the truck and noticed a stain that appeared to be blood, court documents state

The victims’ bodies were found Sunday, a day after the four initial suspects were arrested, in rural Texas County about nine miles from where their car was found abandoned.

Prosecutors have not decided whether to seek the death penalty against the suspects. Four of them appeared in court Wednesday without attorneys present.

“I would hone in on Grice,” Grace added. “He’s scared and he’ll talk.”
