WILKSBORO, N.C. — Missing Tennessee toddler Evelyn Boswell's grandmother waived extradition during an appearance in a North Carolina courtroom Monday, telling the judge she is anxious to return home and resolve the situation.

Angela Boswell, 42, of Kingsport, Tennessee, and her boyfriend, William McCloud, both were arrested on fugitive warrants in Wilkes County, North Carolina, on Friday. McCloud also waived his right to challenge the extradition.

Boswell was transported to Sullivan County, Tennessee, custody on Monday afternoon, the Sheriff's Office confirmed. McCloud remained in North Carolina.

Both were being sought for questioning in the 15-month-old Sullivan County girl's disappearance.

The pair were arrested while traveling in a 2007 BMW, hours after the Tennessee Bureau of Investigation announced that authorities were searching for the car, reported stolen, in connection with the ongoing search for Evelyn.

The girl, who has been the focus of an Amber Alert issued Wednesday night, was not with her grandmother and McCloud when they were captured.

"I'd like to get back there and get this situation with my granddaughter resolved," Boswell told Wilkes County District Court Judge David Byrd.

McCloud, 33, of Bristol, Tennessee, claimed the BMW was a gift from Evelyn's mother, Megan "Maggie" Boswell.

"I had no idea anything had went wrong with the car," he said. "Apparently her daughter hadn't paid for the car. Neither of us was aware of anything about that."

Boswell and McCloud each are charged in Sullivan County with theft of property over $2,500 in connection with the stolen car. Boswell also faces a violation of probation charge.

It was not immediately clear why the couple were in North Carolina amid the search for Evelyn.

According to court records, McCloud, who currently has a Bristol, Tennessee, address, was charged with misdemeanor assault and battery in Wilkes County while living there in 2010. The charge later was dismissed.

Sullivan County Sheriff's Office detectives traveled to Wilkesboro to interview Boswell and McCloud over the weekend about Evelyn, a Blountville toddler who has been missing for two months.

Evelyn vanished in a confounding case that authorities have said is rife with conflicting and inaccurate information. TBI issued an Amber Alert for the girl on Wednesday night at the request of the Sullivan County Sheriff's Office.

TBI initially said Evelyn hadn't been seen since Dec. 26, but officials said Friday that it was more likely she was last seen by a babysitter on Dec. 10 or 11. She wasn't reported missing until Feb. 18, according to law enforcement officials.

Evelyn, who is 15 months old, was last seen wearing a pink tracksuit, pink shoes and a pink bow.

Police also said the missing girl's mother was involved in a car sale that allegedly devolved into a vehicle theft.

“This is unlike anything I have ever seen,” said Jeff Cassidy, the Sullivan County sheriff.

TBI spokeswoman Leslie Earhart said Sunday that the FBI has been assisting TBI and Sullivan County in the investigation since the Amber Alert was issued Wednesday.

Evelyn's mother, Megan Boswell, has full custody of the child. Her father, Ethan Perry, is in the military, stationed in Louisiana. Both the child's mother and father, who are not married, have been involved in the investigation, Cassidy said.

Cassidy personally offered a $1,000 reward to anyone who came forward with information that leads to the child's safe return. He asked others to contribute, too, "to bring sweet Evelyn home."

As of Saturday night, that reward total has reached $56,000.
