VonTrey Clark is back in the United States after being extradited from Indonesia. His plane landed shortly before midnight.
Clark was then brought to the Bastrop County Jail where he was arrested and booked on a charge of Capital Murder of Multiple Persons.
The charges are connected to the death of Samantha Dean, Clark's girlfriend, who was also seven months pregnant.
Authorities says Clark orchestrated her murder. A press conference is scheduled for 1:30 p.m. today to discuss the case.
