More than 100 police officers are hunting for a suspect in the murder of four people, including three children, in a mountainous area in northern Vietnam, authorities said.
Police of Lao Cai Province said the suspect is identified as Tan Lao Lo, 24, who lived in near the victims' house in Bat Xat District.
Lo is believed to have fled after he allegedly murdered 22-year-old Tan Ta May, her two children and her niece on Tuesday.
May's husband Tan Ong Nai was at work when the crime took place.
