The ex-boyfriend of Florida mother Cassie Carli, who was found dead in Alabama in April 2022, was indicted by a federal grand jury on a new charge this week.

Marcus Spanevelo, 35, is now charged with kidnapping resulting in death, according to a Wednesday announcement by U.S. Attorney for the Northern District of Alabama, Prim F. Escalona, and Federal Bureau of Investigation Acting Special Agent, Felix A. Rivera-Esparra.

If convicted, the punishment for the new charge is life in prison or death.

Spanevelo was also indicted on an abuse of corpse charge in December, two months after his extradition to Alabama.

Carli, 37, was found buried in a shallow grave inside a barn on Highway 11 in Springville, Ala., in April 2022.

Her disappearance on March 27 stirred up national attention after she was last seen meeting Spanevelo in the parking lot of a Navarre, Fla., restaurant for a custody exchange of their 4-year-old daughter.

Fox News Digital previously reported Carli had considered purchasing a gun and obtaining a concealed carry permit out of concern for her safety. Spanevelo was also ordered to pay her $5,920 in overdue child support just days before she vanished.

Investigators later recovered Carli's vehicle with her purse still inside. They also confirmed the couple’s daughter was safe.

An autopsy completed by the St. Clair County Coroner's Office in October found Carli's cause and manner of death to be "undetermined" with "no obvious signs of trauma."
