Manila: A Filipino man on Tuesday killed his 7-year old daughter over his wife’s refusal to return home after three months in Canada and posted the girl's lifeless body on Facebook.

Mark Alvin Manliclic confessed on social media and posted a picture of Angel Mark Cathlene’s body after killing her, in one of the Asian country's most graphic portrayal of violence on social media, authorities said.

“I could not explain why I did it,” the 31-year-old Manliclic reportedly said.

Family members said they noticed the husband and wife, an overseas worker, arguing on Facebook, because she had not been answering his messages sent to her mobile phone.

“He wanted his wife to return home,” a family member said, adding that he also threatened to kill their child if the wife did not return home.

It's not the first time such a tragedy or horrific incident had been enabled by social media. Facebook in October had taken down a video of a beheading after massive public outcry against graphic violence. 

Manliclic had tried to kill himself a few days earlier, but his daughter stopped him, the same family member said.

Police found the girl’s body at the family house on M. Aquino Street on Tuesday afternoon, after Manliclic reported what happened to his relatives.

She sustained wounds in her back, neck, and stomach, police said, adding that Manliclic told his mother in the United States about what he did, also on Facebook.

Some 10 million Overseas Filipino Workers are based worldwide. They represent 10 per cent of the country’s population of 100 million.

“The incident clearly describes the social cost of a government policy allowing parents to be separated to earn money abroad,” a sociologist said.

“We could not explain why it happened,” said Chief Inspector Rodelio Marcelo, head of the Quezon City Police District’s Criminal Investigation and Detection Unit.
