Police in the Central Highlands province of Lam Dong arrested Saturday a 19-year-old boy who killed his mother and buried the dead body in front of their house after she refused to give him money for game playing two days earlier.
Nguyen Van Tai a game addict in Bao Loc City is being detained while investigations are still under way, newswire Dan Tri reported.
According to initial investigations, on August 18, Tai asked his 44-year-old mother, Bui Thi Hong Nhung, for money to satisfy his game addiction.
Nhung refused to give him the money and the two started to argue.
Tai picked up a wood stick and repeatedly beat up his mother until she died.
He allegedly dug up a hole under the rock garden in front of their house and buried the dead body in it.
After he cleaned up the blood stains at the crime scene, he went out as if nothing happened, the police said.
According to Dan Tri, after Nhung's neighbors did not see her for a couple of days, they asked Tai about her and were told she had been gone to HCMC for health check-up.
The neighbors felt something suspicious and informed Nhung's relatives of her absence.
On August 20, when the relatives came to her house, they found a pile of sand in the rock garden. They later excavated Nhung's body wrapped in a sack, covered by sand.
Tai was arrested as soon as the police arrived at the house. He confessed to killing his mother afterwards.
According to the police, Nhung lived with his son in the house and made a living by child care.
Tai neither goes to college nor has a job, police said.
