Law enforcement officers recovered the remains of 37-year-old Cassie Carli on Saturday night in a barn in Springville, Alabama, located some 300 miles away from Navarre Beach, Florida, where she was last seen alive, supposedly to collect their daughter from her ex, scheduled for a public setting.

Marcus Spanevelo, 34, Carli’s ex-boyfriend and the father of her four-year-old daughter, Saylor, was arrested in Tennessee on Sunday on charges of evidence tampering and giving false information. More charges are pending for Spanevelo following the results of the autopsy, according to authorities.
Spanevelo arrest comes almost a week after Carli from Navarre, Florida went to see him in Tennessee nearly a week after she went to see him to pick up their four-year-old daughter, Saylor.
After his arrest her family said they were ‘relieved’ and hoped to find ‘more answers.’ 

Spanevelo was arrested in Lebanon, Tennessee, around 10 a.m. on Saturday and has been charged with tampering with evidence, giving false information concerning a missing person investigation and destruction of evidence. 
‘Spanevelo was arrested based on a Santa Rosa County Sheriff’s Office Major Crimes warrant which was signed by a judge,’ the Santa Rosa County Sheriff’s Office wrote in a press release.
‘We are cautious as to the information being released due to the sensitivity of this case.’

Carli’s sister Raeann posted a video on Facebook reacting to the arrest, saying: ‘We are a little relieved to know that Marcus is in custody, and we’re hoping that can bring us some more answers and closer to finding Cassie.
‘Like I said, now that he’s in custody, hopefully we can get a few more answers on her disappearance. We’re going to bring Cassie home.’ 

According to text message and Facebook messenger exchanges between Spanevelo and the family prior to the discovery of Cassie Carli’s body, the he’d claimed that his ex had been ‘acting crazy’ and asked him to drop her off somewhere in Destin, Florida, where her friend lived.
Raeann Carli, Cassie’s younger sister, reached out to Spanevelo on Facebook last Tuesday, asking about her niece, reported Fox 13.
‘Is Saylor with you?’ she wrote. ‘Please Marcus [sic]…this is NOT like my sister! She has been doing great & was supposed to star a new job! I hope you will at least cooperate with the police/let them know you have Saylor. She is now a missing person.’

Cassie Carli’s family speaks amid urgent search for missing Florida mom 

Spanevelo replied, telling Raeann Carli that Saylor was with him.
‘[Cassie] wanted to be dropped off in the middle of nowhere in Destin with Saylor [sic]..I told her I wouldn’t let Saylor go like that.’
Spanevelo added that police had already reached out to him, asking questions.
This exchange was in the same vein as the one Spanevelo reportedly had with Carli’s dad a day earlier. Spanevelo allegedly told Andrew Carli that Cassie had asked him to ‘drop her off in the middle of nowhere in Destin’ so that she could stay with a friend.
Andrew replied that the woman he was referring to, ‘moved to Alabama a while ago. Cassie would never have you drop her off anywhere.’
Spanevelo told Andrew that he had left with Saylor.
On Saturday night Cassie Carli’s remains were found buried in a shallow grave inside a barn on US 11 in Springville, Alabama, Santa Rosa County Sheriff Bob Johnson said. 

Detectives from Santa Rosa County traveled to Birmingham, Alabama, on Wednesday and located Marcus Spanevelo and his daughter, Saylor, four, three days after the girl’s mother, Cassie Carli, vanished in Navarre, Florida, located more than 260 miles away. 
Authorities said the former couple’s child is ‘safe’ and ‘search efforts for Cassi Carli remain underway.’  he Maury County Sheriff’s Office in Tennessee said the father has been booked into jail. 

Carli’s car was located on Tuesday in Navarre with her purse inside, raising concerns for her well-being, Santa Rosa County Sheriff Bob Johnson said during a press conference on Thursday, adding that there has been no activity on the missing woman’s phone or credit card since Sunday.  

Johnson said his detectives still do not know if Carli has been the victim of a crime, but she is considered to be missing and endangered. 
Carli had arranged to meet up with Spanevelo to exchange custody of their daughter at around 7 p.m. in the parking lot of Juanita’s Grill at Navarre Beach.
Every day the family and community members have met in the parking lot of Juanita’s Grill at Navarre Beach – where her car was found – to search for her, according to WEAR-TV.
Her father, Andrew Carli, told DailyMail.com that before going, she told him, ‘”I’ll be right back.” She never came back.’ 
Andrew said Spanevelo, whom he described as a ‘narcissist,’ had a turbulent relationship with his daughter after their split. He claimed that prior to her disappearance, Carli had obtained a court order compelling her ex-boyfriend to pay her $6,000 in child support.
Carli’s dad also said that Spanevelo would not take his calls or answer his text messaging asking about Carli. 
Carli’s young sister Raeann told Fox News her sister felt ‘extremely unsafe’ around Spanevelo and had warned her family about him. 
‘Just in general, with her relationship with him, it has always been, she has had some fear of him,’ her sister said.

‘He’s always controlling, and tried to be manipulative, and she had some fear of him in the past. And what he’s capable of, or planning maliciously towards her,’  Raeann said.
On the day, the custody exchange was set to take place at a neutral spot.
Raeann, who lives in North Carolina, told NBC’s Dateline that Cassie and her ex typically met at a Walmart located in Destin, halfway between Navarre and Panama City, where Spanevelo lives. 
The custody exchange was set to take place at a parking lot at Navarre Beach.
But for an unknown reason, they decided at the last minute to change their meeting place Sunday. 

Carli lives with her dad in Navarre, Florida. Nearly four hours after leaving home on Sunday to pick up Saylor, her father, received text messages from his daughter’s phone, telling him that she was having problems with her phone and her car.
Carli never made it home that night, and she was still missing the following day, Monday, when her father came home from work he discovered that his daughter has not returned.  
That evening, nearly 24 hours after her last sighting, Andrew Carli contacted the authorities and reported his daughter missing. 
Santa Rosa Sheriff’s deputies located Carli’s vehicle on Tuesday morning at Navarre Beach, but she was nowhere to be found. Her purse was discovered inside.  

Four-year-old Saylor has been found safe with her dad, still her mother failed to return home, sparking a massive search involving law enforcement officials and volunteers.
Carli’s friend Sam Graves, who organized a search party in Navarre on Tuesday, accused Saylor’s father, [Spanevelo], of falsely claiming that he had brought Cassie to Graves’ house after she ‘freaked out’ on Sunday. 
Andrew Carli, Cassie’s dad, called those claims ‘bulls***,’ arguing that Spanevelo never even met Graves. 
Graves said that Spanevelo, a Brazilian national, previously had threatened to take Saylor out of the country. She also alleged that Spanevelo an ‘abuser,’ although he’d never been charged with any crime related to Carli.   
Graves grimly remarked said that all indicators are pointing to a ‘worst-scenario ending.’  

Carli had just started a new job at the nearby Eglin Air Force base the day before. Her sister said Carli told her that her first shift went well. 
Raeann Carli said that her sister is in a great physical and mental shape, and is known for her fun and outgoing personality.
