The charm, it was claimed, was his inheritance from his late herbalist father.
A family source told the News Agency of Nigeria that Agugu committed the crime at his Kisaghyip village farm in Bassa Local Government Area of Plateau.
The source said that Agugu, after killing his mother, removed N20,000 from her and used it to buy a mobile phone, a shirt and a pair of slippers.
Spokesman of the Plateau Police Command, Mr. Tyopev Terna, confirmed that the suspect was being held, but declined further comments.
“Investigation is ongoing. The details are not ready. Please understand with us and be patient,” he told NAN on phone.
But Agugu, who spoke with our correspondent, said he killed his mother because she refused to give him a charm that was his inheritance from his late father.
“When I was 14 years old, my late father, who was a native doctor, showed me a charm that enabled him to disappear and reappear at will. He promised to hand over the charm to me when I turn 18.
“On his dying bed four years ago, he gave my mother the charm and asked her to give me when I turn 18. But I am now 18 and she has refused to give it to me.
“On this fateful day at the farm, I asked her about it, but she threatened to throw the charm into the river if I disturbed her too much.
“Her response infuriated me and I suddenly felt that she was of no value as a mother. I immediately slaughtered her with the knife I was using to harvest potatoes.
“After slaughtering her, I dumped her body in the bush,” he said.
Senior brother to the suspect, Mr. David Adau, has, however, dismissed the suspect’s claim that he killed their mother because of a charm.
David narrated, “Prior to the incident, the family had faced several problems with Agugu. He was fond of stealing and causing trouble.
“I believe he killed our mother because of the N20,000 I gave her a day before the incident. I work at the mines in Barkin-Ladi, and I usually give my earnings to our mother to keep for me.
“I handed over the money to my mother in his presence. In fact, when I gave her the money, she expressed fear that Agugu could attack her to get the money. He has proved her right.”
David said that on his return from work a day after the incident, he asked after their mother, but Agugu said he did not know her whereabouts.
“He said he did not know where my mother was. Later in the day, I saw him with a new mobile phone, a new shirt and (a pair of) slippers, and I became curious.
“I asked him where he got them from, but he could not give me satisfactory answers.
“Other family members joined me and we kept pestering him over our mother, but he insisted he knew nothing.
“Three days later, I invited the police to question my brother. That worked immediately, as he confessed to killing her,” he said.
David said the suspect later led family members and the police to the farm where they saw the already decomposing body of the woman.
