Mystery as male and female firefighter ex-high school sweethearts are found dead in car a week after vanishing

Two Georgia firefighters who were once high school sweethearts were mysteriously found dead in a car in Tennessee following a week-long search for the pair. 

Reagan Anderson and Chandler Kuhbander, both 24, vanished on June 24 from a Crunch gym parking lot, with authorities launching a multi-state search after the pair were believed to have left in Anderson's car. 

On Sunday, their bodies were found over 450 miles away inside the vehicle, however law enforcement has not offered any details over their cause of death or the manner in which they were found. 

Kuhbander's mother said they had dated for seven years in a 'toxic' relationship, and claimed that Anderson took their recent breakup badly and threatened to kill herself and was harassing her son. 

Reagan Anderson and Chandler Kuhbander, both 24, were tragically found dead in her car on Sunday, over 450 miles from where they vanished a week ago 

The couple of seven years had recently broken up, and Kuhbander (pictured) had reportedly said Anderson was harassing him and threatened to kill herself 

Kuhbander was last seen leaving a Crunch fitness in Savannah, Georgia, where his mother Jane said he was seen walking 'out of the building, and he looks very comfortable, like he just had his workout.' 

'He doesn’t look rushed as he walks through the parking lot,' she told WJCL. 'After that, we don’t see him again.' 

Kuhbander's mother said she saw surveillance footage showing Anderson circling the gym's parking lot several times while he was inside. 

Security footage showed him head towards his car, however Kuhbander's mother said she believes he got into her Ford Focus 'under duress.' They claimed his car never left the parking garage and his family later went to retrieve it.  

It appears the couple began driving together, with Anderson last seen in surveillance footage at a gas station in South Carolina that day, at the same spot where Kuhbander's phone last pinged off a cell tower. 

Officials have not said why the former couple were driving together or what their intended destination was.

After a week-long search that saw both families plead for help in finding the two, Hinesville Police in Georgia said on Sunday that they were both found dead in the car in Cocke County, Tennessee. 

Kuhbander's mother said she last spoke to her son a few days before he disappeared, and claimed that he told her Anderson had been continually harassing him following their breakup. 

'He was telling me she was blowing up his phone, and he said that she had threatened that she was going to commit suicide,' she said. 

'And it's not the first time that she's done it.' 

Two days before they disappeared, Anderson was arrested after spotting Kuhbander on a date with another woman and allegedly keying his car. 

Kuhbander's mother told WJCL that she posted bail, and was facing charges of criminal damage to property and disorderly conduct. 

She alleged that Anderson wrote a suicide note to her son on the day they disappeared, and said he continued to console her despite their breakup in the days beforehand. 

'He's very driven to do the right thing and make sure people are safe,' she added to Court TV. 'He really does care about Reagan.' 

Two days before they vanished, Anderson reportedly keyed Kuhbander's car after she spotted him out on a date with another woman 

Kuhbander's heartbroken family said they were 'trying to find the words to say goodbye' after his shock death 

Amid numerous unanswered questions over what happened to the pair or how they died, an autopsy is reportedly being prepared to determine their cause of death, 

'Details pertaining to the discovery of their bodies, vehicle and events leading to their deaths are not available at this time,' cops said in a statement. 

In a heartbreaking Facebook post, Kuhbander's sister said she was 'trying to find the words to say goodbye, but I can't.' 

'It’s tearing me apart to even think about not having you here. Never in my life did I think I would have to be doing life without you,' she wrote. 

'It’s always been my two big brothers but now it’s just me and Xander. We will honor you in every way possible. No one will ever not know who you are and how good of a person you are. I love you forever bub.'
