The ex-boyfriend of a Florida woman whose body was found in a shallow grave in Alabama has been charged with a felony crime in St. Clair County.

District Attorney Lyle Harmon on Monday said a warrant has been issued against Marcus Spanevelo for abuse of corpse in connection with the death of Cassie Carli.

According to Alabama law, a person commits the crime of abuse of a corpse if he or she knowingly treats a human corpse in a way that would “outrage ordinary family sensibilities.” The charge is a Class C felony punishable by one to 10 years in prison.

Spanevelo has not been charged in Carli’s death.

On Friday, Harmon said, Spanevalo signed documents agreeing to extradition to Alabama. On Monday he remained in the Santa Rosa County Jail in Florida.

“First and foremost, our hearts and prayers go out to the family of Cassie Carli,’’ Harmon said in a statement released Monday. “Currently, a massive investigation into Cassie Carli’s death is ongoing and involves three states and their respective state agencies. These agencies continue to work tirelessly with each other for the common goal of justice.”

Harmon’s announcement comes after Florida officials last week dismissed charges against Spanevelo there. He had been charged with tampering with evidence, giving false information concerning a missing persons investigation and destruction of evidence in Santa Rosa County.

“In an effort to prosecute the strongest case, and after communicating with law enforcement agencies in both states, the Office of the State Attorney believes that in the interest of justice, the actions of Marcus Spanevelo are most appropriately prosecuted in Alabama,’’ WALA television station reported, quoting court filings. “Spanevelo will be transported by law enforcement to Alabama.”

The Florida dismissals followed the results of the final autopsy report for Carli which yielded no definitive answers on how she died. Both the cause and manner of her death were deemed undetermined.

Harmon said Alabama authorities have worked closely the State Attorney’s Office in Florida and the Sheriff’s Office in Santa Rosa County in trying to discover who and what caused Carli’s death.

“While my office has no authority to dictate the criminal charges which the State of Florida may bring or the ability to influence the timing of how they travel through their court system, I appreciate the open and candid discussions that have taken place between the Office of the State Attorney in Florida and my office regarding this investigation,’’ Harmon said. “I will continue to lend them whatever assistance the law allows with the hope that the Carli family will have closure.”

Harmon said the abuse of corpse charge against Spanevelo has been pending since May and a hold had been placed on Spanevelo while he was in custody in Florida.

Since Spanevelo has now agreed to extradition, he will be brought to Alabama. The charge against him is eligible for bond, Harmon said.

“While the investigation into the cause and manor of Cassie Carli’s death are ongoing, this current charge does not limit any agency or state from pursuing additional charges at the appropriate time,’’ Harmon said. “I am prevented by the Alabama Rules of Professional Conduct from discussing matters involving current investigations and active cases other than the information that I provided above. Therefore, I will not be making further statements regarding this investigation unless additional charges are brought.”

Carli disappeared March 27 after meeting Spanevelo in a restaurant parking lot in Navarre, Florida to pick up their daughter following a visit with her father.

On Monday, March 28, Carli’s father reported her missing to Santa Rosa sheriff’s authorities.

The following day, her vehicle was found in the parking lot behind the Juana’s Pagodas restaurant where the pair had met for the child exchange. Her purse and its contents were inside the vehicle.

On Saturday, April 3, Carli’s body was found in a shallow grave in a barn on Highway 11 in Springville. The vacant property was one of two addresses in Springville that authorities had for Spanevelo.

Spanevelo had been living and working in Springville in the months prior to Carli’s disappearance.
