A North Carolina teenager is accused of decapitating his 35-year-old mother in a horrific scene that left a sheriff’s deputy in “terror.”

The first deputy to arrive at the scene of the grisly slaying found Oliver Funez, 18, “with his mother’s head in one hand and a large butcher knife in the other,” according to the Franklin County Sheriff in Zebulon, North Carolina, reported WNCN-TV.

The Charlotte Observer reported that Funez is an illegal immigrant from Honduras. The Observer noted: “When Funes-Machado saw officers, he reportedly placed the head on the ground and was arrested.”

The suspect’s name is sometimes given as Oliver Funes Machado and Oliver Mauricio Funes Machada. The motive has not yet been released.

The attack occurred around 1 p.m. inside a home on March 6, reported the television station. ABC 7 reported that the attack occurred in what is normally a “quiet corner” of Franklin County, North Carolina.

According to The Associated Press, a neighbor described them as a “quiet family with the standard white picket fence, trampoline, playground in the back.”

According to ABC 11, “two young girls found in the home were unharmed. A fourth child was at school when the incident happened.”

The Sheriff, Kent Winstead, told 14News that, when deputies arrived, “he was with the decapitation in his hand, and it was a gruesome scene. The oldest son killed his mother.”

Horrifically, authorities allege that Funez beheaded his own mother with a butcher knife.

“It looked to be a large butcher knife, the weapon that was used,” said Sheriff Winstead, according to ABC 11.

A neighbor said the deputy who first arrived at the scene was deeply shaken by what he saw. “He just looked like he was just blown away. I mean, he was just in terror. He was just so upset,” the neighbor told 14News.

A neighbor told the television station, “I can’t imagine how anyone could do that to anybody, much less your own mother.” The sheriff told 14News it wasn’t yet clear how many wounds the mother had suffered.

According to WRAL-TV, Funez “is originally from Honduras and it was not immediately clear whether or not he is a U.S. citizen.”

However, the conservative site Breitbart reported Funez is an illegal immigrant, quoting ICE Communications Director Bryan Cox as saying, “ICE Enforcement and Removal Operations (ERO) has issued a detainer for Oliver Funes-Machado, an unlawfully present Honduran national, following his arrest March 6 on local charges in Franklin County, North Carolina.”

The Charlotte Observer also confirmed that Funez was in the country illegally and reported that ICE has filed a detainer to hold him. “It’s believed Funes-Machado (Funez) was among the youths who qualify for DACA status,” the newspaper reported of the teenager.

The television station said that the suspect finished 10th grade at Rolesville High School, and quoted the Franklin County District Attorney as saying his “mental state will be a primary interest.”
