Search warrants are issued in the case of a teen who decapitated his mother and say told a 911 operator he did it “because I felt like it.”

Oliver Mauricio Funez Machado, 18-year-old, is being held in “safekeeping” as he undergoes a mental health evaluation at Central Prison while his case moves for further investigation.

Machado is being held without bond on a first-degree murder charge after authorities say he killed his mother with a knife at their home Monday afternoon.

Walter Funez said his son had just left a mental facility last Tuesday. He called what his son did “monstrous” – saying no son should ever do that to a dad.

A search warrant also revealed Machado told the 911 operator he stabbed 35-year-old Yesenia Funez Beatriz Machado “like 8 times.”

According to court documents, Machado took four different medications for psychosis and schizophrenia.

“Certainly some cases are worse than others, but you just work through the issue and remember what your job is and your job is to make sure that the rules are followed and that your client gets the fairest and best resolution within the boundaries of the law,” Boyd Sturges, Machado’s defense attorney explained.

Sturges said he expects the case to center on Machado’s mental state.

“Under our criminal justice system, a person’s mental health can be relevant depending on a number of factors and that is what I think we’ll be looking at going forward,” he said.

Sturges still doesn’t know for how long Machado has suffered from mental health issues, and he’s he’s only gotten it second and third hand that the teen had been committed to mental health facility recently.

“The horrific nature of this particular crime would indicate this is not a normal situation. and so you would have to assume at least from the beginning that that (mental issues) might be a factor,” he offered.

The federal officials also said Tuesday that Machado 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.

Deputies said two young girls found in the home were unharmed. A fourth child was at school when the incident happened.

Walter Funez said his younger children are now with him and are doing OK. He also said right now he is focusing on preparing funeral services for his wife.

The community is planning a vigil in memory of his wife on Friday.
