Machada is being held without bond on a first-degree murder charge after deputies say he decapitated his mother at their home on Morgan Drive near Stonehill Drive just south of U.S. Highway 64 Monday afternoon. The area is east of Zebulon – near the Wake County line.

At a a preliminary hearing Tuesday, both the prosecution and defense said they expect mental health to be an issue in the case. According to court documents, Machada took four different medications for psychosis and schizophrenia.

Federal officials also said Tuesday that Machada is in the country illegally and they’ve issued an immigration detainer for him.

“ICE is focused on identifying, arresting and removing public safety threats, such as convicted criminal aliens and gang members, as well as individuals who have violated our nation’s immigration laws,” a U.S. Immigration and Customs Enforcement spokesperson told ABC11.

Local investigators called it a horrific crime.

“Officers encountered the suspect holding a knife and, as reported, also holding his mother’s head in the other arm,” Franklin County Sheriff’s Office Chief of Staff Terry Wright said.
