ROGERSVILLE, Tenn. -- (KFOR) -- An Amber Alert originally issued for Carlie Trent in Tennessee on Thursday was extended into Missouri on Tuesday.
Investigators say she and suspect Gary Simpson, 57, may have been spotted in Otterville, Mo., on Monday. Otterville is just east of Sedalia, and about 110 miles from Kansas City.
Authorities are searching for the 9-year-old girl who was taken from school by an uncle with no custodial rights, according to a news release from the Tennessee Bureau of Investigation.
Investigators know Simpson bought clothing and camping items, so it's possible they're in the woods or at a campground.
On Tuesday, authorities described items Simpson bought at a Walmart before the incident. The list includes things apparently for Carlie, such as child-sized khaki pants, a nightgown, a bikini, underwear, lipstick, nail polish and a child-sized camp chair.
Simpson also bought a T-shirt and black pants for himself, authorities said.
Carlie is a white female, 4 feet 8 inches tall, weighs 75 pounds and has blonde hair and blue eyes. She was last seen wearing a black and gray tank top and blue jeans.
Simpson is a white male, 5 feet 10 inches tall and weighing 157 pounds. He is balding and has brown hair and eyes.
He was last seen wearing a brown cap, a dark-colored shirt and jeans and driving a white 2002 Dodge conversion van with Tennessee registration 173GPS. The van has a dark stripe down the middle with light gold running boards and paint chipping off of the hood.
The U.S. Marshals have increased their reward to $5,000 for information leading to Trent's safe recovery and Simpson's arrest.
Trent's pediatrician has also offered $10,000 reward.
Authorities say anybody with information should contact the Rogersville Police Department at 423-272-7555 or TBI at 1-800-TBI-FIND.
