FRANKLIN COUNTY, North Carolina (WTVD) -- In a 911 call released Thursday, 18-year-old Oliver Mauricio Funez Machado speaks in a flat monotone as he tells an operator that he killed his mother "because I felt like it."
"What was she doing? Did she make you mad? Or what happened?" the dispatcher asks.
"Yes, she made me mad," Machado responds.

The unemotional quality of Machado's tone is striking as the clearly horrified 911 operator continued to question him about the brutal killing. The dispatcher was constantly checking on the two children, ages 2 and 4, in the home at the time of the murder, but Machado said he wasn't going to hurt them.
He told the operator he stabbed 35-year-old Yesenia Funez Beatriz Machado "like 8 times."
Deputies arrived at the home east of Zebulon to find her decapitated and her body mutilated.
Machado's attorney, Boyd Sturges, said he will be undergoing a mental health evaluation during the next several weeks. Charged with first-degree murder, Machado is being held without bond at Central Prison which is better equipped to handle his needs, Sturges said.

According to court documents, Machado took four different medications for psychosis and schizophrenia.
Federal officials also said Tuesday that Machado is in the country illegally and they've issued an immigration detainer for him.
Deputies said two young girls found in the home were unharmed. A fourth child was at school when the incident happened.
Yesenia Machado's husband, Walter Funez, told ABC11 on Wednesday that his younger children are with him and are doing OK. He also said right now he is focusing on preparing funeral services. The community is planning a candlelight vigil in memory of his wife on Friday.
