He is wanted for the August 2016 murder of Truc Quan "Sandy" Ly Le in Charlotte, North Carolina.
In 2016, a then-17-year-old Castillo worked at a Showmars restaurant in Charlotte, North Carolina, and was co-workers with 23-year-old Truc Quan "Sandy" Ly Le.
The two reportedly briefly dated and at some point Le had lent Castillo some money which he never paid back to her.
Castillo was picked up that afternoon by Feaster, who collected him in her red Dodge Caliber and took him to the meeting.
It is believed that instead of repaying her, Castillo forced Le to withdraw all the money from her bank account, possibly with a gun.
[4] Investigators believe that Castillo then drove Le to a wooded area in Cabarrus County where he shot her once in the head, killing her.
Feaster's Dodge Caliber was found abandoned on August 13 in the 11000 block of Dulin Creek Boulevard in Charlotte.
On October 22, Feaster was extradited back to the U.S. and was arrested by the Harris County Sheriff's Office near Houston, Texas.
She was eventually transferred to Mecklenburg County Jail where she posted bond and was released on January 18, 2017.
