FLORENCE, Ala. – Investigators are working to determine if a vehicle discovered in Evansville, Indiana, is linked to the Alabama prison escapee and fugitive prison guard who fled from an Alabama jail late last month. 

A spokesperson for the U.S. Marshal Service confirmed to Fox News Digital on Monday that agents believe they have found a second vehicle used by the pair and then abandoned in the days following their escape from the April 29 escape from the Lauderdale County Detention Center in Florence, Alabama. Local news station WAAY 31 suggests it is the same vehicle reported stolen from Tennessee shortly after the couple ditched the getaway car used earlier in their escape.

The vehicle found in Indiana was described as a dark blue 2006 Ford F-150 with nothing inside, according to authorities. Marshals received a tip on Sunday night about the vehicle, which agents discovered at a car wash in the 2000 block of South Weinbach Avenue in Evansville.

New surveillance images, which were provided by authorities on Monday, show a man wearing a red-colored collared shirt, khakis, and a baseball cap, and standing next to the F-150 in question. A different photo shows the man, who was also wearing sunglasses, with what appeared to be a tattoo on his right forearm.

Photo provided by USMS on May 9, 2022, shows the 2006 Ford F-150 had been abandoned at a car wash in the 2000 block of South Weinbach Avenue in Evansville.

The photos show a timestamp dating back to Tuesday, May 3. No woman could be seen in any of the photos provided by authorities. 

Lauderdale County Sheriff Rick Singleton confirmed the truck was taken in Tennessee, but noted that investigators were still working to "absolutely" confirm that the man seen in images was White. 

"But that is the truck that they were looking for," he told Fox News Digital. "So, that sounds like a promising lead."

He said there was no information about any other vehicles the couple could now be using.

Marshals have previously shared photographs that showed the numerous tattoos Casey White wore on both sides of his chest, his arms and his back. The tattoos include a horseshoe emblem with a red-colored flower on his left pec; ink encompassing his full right shoulder and arm and another tattoo covering part of his left arm; and a confederate flag on his back emblazoned by the words "Southern Pride" in a crude script. 

LAW ENFORCEMENT IMAGES SHOW COUPLE'S APPEARANCE 

Marshals describe Casey White as being 6-foot-9 inches tall and about 330 pounds, with brown hair and hazel eyes. Law enforcement images show he has worn his hair in various ways through the years, including shaved, shaggy and with a buzz cut. 

He stands significantly taller than Vicky White, who is 5-foot-5 inches and approximately 145 pounds. She has brown eyes and is said to walk with a "waddling gait." 

USMS images from late Thursday also include photos showing what Vicky White would look like if she changed her hair color from her normal blonde to a darker shade, or if she shortened it from her typical length.

Monday marked Day 11 of the manhunt for the pair, who are not related. Vicky, 56, and Casey, 38 had been in the throes of a "jailhouse romance" when they slipped away from the Lauderdale County Detention Center in Florence, Alabama, on April 29, Singleton previously told reporters.

Vicky White was charged Monday with identity theft and second-degree forgery, according to a warrant for her arrest released that day. She was previously charged with a felony for permitting/aiding an escape. 

"These charges stem from her using an alias to purchase the vehicle, a 2007 Ford Edge, used to facilitate the escape," officials said.

On Friday, the USMS revealed they had received a tip around 11 p.m. Thursday about a vehicle matching the description of the 2007 Ford Edge, and had since been able to confirm the SUV was the same one used by the fugitive pair. 

With the help of the tip, they were able to track the vehicle to a tow lot in Williamson County, Tennessee, about two hours north of where the manhunt first began, the office said. 

Tennessee's Williamson County Sheriff's Office said in a Friday tweet that the fugitive vehicle had been reported abandoned "a week ago" in Bethesda. "There is NO sign the two are still in our area," the tweet stated.

Authorities later shared images showing that the SUV’s rear bumper had been spray-painted a distinct green color before it was discovered. The SUV was returned to Alabama investigators just after 12:30 p.m. Monday for further investigation. 

The vehicle was pulled by a truck with Alabama license plates into the Lauderdale County courthouse parking lot, where investigators with cameras took pictures and confirmed the VIN number before towing it to a storage facility.

Singleton said his office is investigating whether the pair ditched the Ford SUV because the vehicle broke down. 

"I think that vehicle was abandoned," he said. "I don’t think as part of the plan."

He said his office has already received hundreds of tips so far, and he is "confident" that investigators would track the fugitives down. 

"Every day we get new leads. I’m confident that’s how we’re gonna catch them," he said. "Somebody is gonna call in a tip, and it’s gonna be the tip."

Dave Katz, CEO of Global Security group and a former DEA special agent who took part in the 1990 manhunt for the mobster Constabile "Gus" Farace, previously told Fox News Digital that the public should "assume" that Casey's White's history of carjackings "allows them to change transportation easily."

Officials are now offering a reward of up to $25,000 for information that leads law enforcement to the couple. Anyone with information on their whereabouts is asked to call the U.S. Marshals at 1-800-336-0102.
