Angela Marie Hill, 25, waived extradition Friday during a court appearance in Elko.
Hill, also known as Angela Atwood and Angela Garcia, was arrested Tuesday, along with with Logan McFarland, 24, near the small town of Oasis, Nev.
McFarland told the judge he plans to fight extradition.
No charges have been filed in Utah against Hill or McFarland. Complaints filed against them as fugitives from justice in U.S. District Court in Utah were dismissed Wednesday.
Court documents filed in both Utah and Nevada strongly suggest that McFarland and Hill are suspects in the double killing of Woody and Ann Fullwood during a burglary at their home in Mt. Pleasant, Sanpete County.
McFarland was charged earlier this month with burglarizing the Fullwoods' home. Days later, he and Hill were arrested.
Police say the couple went on a crime spree that started in Utah and included a carjacking in Wendover. Hill was charged in Nevada with attempted murder for allegedly shooting the carjacking victim as the woman escaped her captors and drove away.
Both Hill and McFarland also were charged in Nevada with kidnapping, robbery and other charges.
Three additional Sanpete County residents now face charges in connection with the Dec. 29 burglary when the Fullwoods were killed: Larry McFarland, 27, Allison Boudreaux, 55, and Damien Flores, 20.
Some time after the killings, Flores called police and reported that he had information relating to a crime in Mt. Pleasant, according to a police affidavit filed in Logan McFarland's case.
He identified Logan McFarland from a photo Flores saw in an online news story, the affidavit states, and told police that on Dec. 29, he was at a party with Hill and Logan McFarland. Flores told police the pair asked to borrow Boudreaux's 1997 Plymouth Breeze "to go to Mt. Pleasant to a 'friend's house.'"
Flores said the pair borrowed the car around 8 p.m. that night and returned just after midnight.
"Mr. Flores said Mr. (Logan) McFarland spoke to him within the residence and bragged to him about having acquired firearms and money, but did not indicate how or where he acquired them," the affidavit states.
Flores said he then went to bed and Boudreaux woke him around 6 a.m. Dec. 30 to tell him that her car was missing. Flores tried unsuccessfully to reach Logan McFarland and ultimately told the man via text message that he would call police if he didn't return the car immediately, according to the affidavit.
Soon after, a man who identified himself as Larry McFarland called Flores and told him Boudreaux's car was on I-15 near Santaquin, the affidavit states. Flores and another woman retrieved the car and found what looked like a jewelry box, a grill, a black plastic box and a metal container in the trunk.
According to the affidavit, Flores feared the items were stolen and made the decision to burn everything but the black box and metal container. Items found in a car, including jewelry, were linked to the Fullwoods.
Larry McFarland, believed to be Logan McFarland's brother, was charged Friday in 6th District Court with obstruction of justice, a second-degree felony. The charges only indicate the crime occurred Dec. 30 in Sanpete County.
He was also charged with purchase, transfer or use of a firearm by a restricted person, a third-degree felony, for an unspecified Jan. 4 event. He was also charged Friday with altering the number on a pistol or revolver, a class A misdemeanor, on Dec. 30.Comment on this story
