UPDATE:  Investigators determined two people photographed in Missouri were not missing Rogersville 9-year-old Carlie Trent and her non-custodial uncle, Gary Simpson.

Thursday, the Cooper County Sheriff's Office issued an Amber Alert when they received a tip that Trent and Simpson were near Otterville, Mo.

Mid-Missouri NBC affiliate KOMU reported the Cooper County Sheriff's Office confirmed the two people in a photo taken in a canoe on the Lamie River are not 9-year-old Carlie and her uncle.  Cooper County investigators spoke with the people in the photograph and said they are residents of Stover.

As of 10:38 p.m. Tuesday, deputies said they will not cancel the Missouri Amber Alert on Carlie until all leads have been investigated.

Earlier, at 10:13 p.m. Tuesday, the sheriff's office said it had "begun to cancel" the Missouri Amber Alert, but people should "continue to be vigilant for Carlie and Simpson."

The Tennessee Bureau of Investigation said Thursday they had received more than 600 tips from 11 different states, but had no confirmed leads or sightings of the Trent and Simpson.

Trent has now been missing for one week.

PREVIOUS STORY: The Tennessee Bureau of Investigation released new surveillance video Tuesday of a 9-year-old girl who was reported missing in East Tennessee last week.

The search for Carlie Trent is now in its sixth day.

The footage shows Carlie Trent with her uncle, Gary Simpson, at a Save-A-Lot store in Rogersville on Wednesday.

Simpson picked up Carlie from school on Wednesday afternoon. According to the Tennessee Bureau of Investigation, Simpson told school officials that she would be absent on Thursday but would be back on Friday.

Simpson previously had custody of Carlie, but custodial rights were recently awarded to her father. The school system had not been updated on the change of custody, which is why Simpson was allowed to pick her up from school.

The TBI issued an endangered child alert on Wednesday and escalated it to an Amber Alert on Thursday morning after Rogersville police filed a kidnapping warrant against Simpson.

At a late-morning news conference Tuesday, Tennessee Bureau of Investigation spokesman Josh DeVine appealed to Gary Simpson directly, asking him to "do the right thing, and bring her home," referring to nine-year-old Carlie Trent.

Items purchased at a WalMart store by Simpson included a pink zebra blanket, green shirt for himself (which he could be wearing), black pants, khaki pants for Carlie and nail polish.

DeVine also said that the TBI still believes that Carlie is in "imminent danger."


(NBC News) - Detectives hunting for a nine-year-old Tennessee girl allegedly kidnapped by her uncle have investigated more than 500 tips but have verified no credible sightings, officials said late Monday.

Agents and intelligence analysts worked to co-ordinate and verify the tips but Carlie Trent's whereabouts remain unknown, the Tennessee Bureau of Investigation said in an update on the Amber Alert.

They believe the pair may be out of view in an isolated area "such as a campground or park," the TBI said, adding that the focus of the search shifted Monday to Upper East Tennessee.

Authorities say Carlie was picked up Wednesday from an elementary school in Rogersville by Gary Simpson, an uncle by marriage.

Simpson, 57, previously had custody of Carlie and her younger sister, but that had since been returned to her biological father, James Trent.

James Trent, who is a single parent, told NBC's Dateline that Simpson regularly helps out by picking his daughters up from school for appointments or events if he had to be at work. However, there were no plans for Simpson to collect Carlie Wednesday.

Surveillance images show the pair inside a grocery store Wednesday evening stocking up on non-perishable items and treats.

"I have to be strong for my other daughter and for Carlie," Trent told Dateline. "But as the days keep passing, it's getting harder."

Carlie's pediatrician is offering a $10,000 reward for information leading to her safe recovery and the U.S. Marshals Service has also announced a $5,000 reward.

The Tennessee Highway Patrol is aiding the effort by conducting helicopter searches.

Simpson was last seen driving a white 2002 Dodge Conversion Van with Tennessee registration 173GPS.

"There are so many places he could be," Trent said. "I don't know what story he's told her, because there is no doubt she wants to be home. This whole thing has puzzled our whole family because everything about that morning was normal."

He added: "I want her to know that she's loved. That she shouldn't believe whatever he's telling her. She should get out, run, scream, do whatever she has to do to get away, because there are so many people looking for her. We'll never give up."

Carlie is described as 4'8" tall, weighing 75 lbs. with blonde hair and blue eyes. She was last seen wearing a black and grey tank top with blue jeans.

Gary Simpson was last seen wearing a brown cap, dark colored shirt and blue jeans.

Anyone with any information regarding Carlie or Simpson's whereabouts is urged to call the Rogersville Police Department at (423) 272-7555 or the Tennessee Bureau of Investigation at 1-800-TBI-FIND.
