Cassie Carli’s body was found Saturday after Spanevelo’s arrest. The body was located in a shallow grave inside a Springville, Alabama barn, according to police reports, Marcus Spanevelo has a connection to the property. He had recently started working in the area where Carli’s body was found.

The Florida mother was identified by a tattoo on her body. An autopsy to determine the cause of death is scheduled for Monday. Cassie Carli disappeared one week ago and was last seen in Navarre Beach, Fla. around 7 p.m. with her 4-year-old daughter, Saylor.

Carli was waiting to hand over her daughter to Spanevelo, according to their custody agreement when both the mother and daughter disappeared. Saylor was found safe two days later with Spanevelo. According to Carli’s family, the Florida mother was fighting with Marcus Spanevelo over custody and the 37-year-old had threatened to hurt her.

Marcus Spanevelo was reportedly the last person to see Carli alive.

“Cassie’s been telling me for the last two years that [Marcus] has been threatening her,” said Carli’s brother Anthony Carli. “She’s always said, if anything happens to me, it’s him.”

Santa Rosa County police said that Carli’s disappearance was “very concerning,” after officers found her purse and other personal items left in her car. Santa Rosa County Sheriff Bob Johnson said, “There were things in the purse … we don’t think she would just up and leave. Usually, you don’t go four days without hearing from them, or them using a credit card, cell phone…so yeah, we’re concerned.”

Cassie Carli’s father said that he got text messages from Spanevelo on the day of his daughter’s disappearance. He said that Carli had asked Spanevelo to drive her “in the middle of nowhere in Destin,” so she could stay with a friend named Stacey. He later received a text saying that Carli was having car trouble and that she would be staying the night with Spanevelo.

Carli’s father replied, “Stacey moved to Alabama a while ago. Cassie would never have you drop her off anywhere. Is her car at your house?” Carli was announced a missing person a day later and her car was found in a restaurant parking lot.

The couple’s daughter, Saylor, is reportedly in the custody of Alabama Child Services.
