A marriage has been arrested in Hong Kong for the alleged murder of a domestic worker whose body was discovered near a waterfall on Monday.

The victim had visible wounds on his forehead, the back of his head and his limbs, but his clothes and belongings remained intact, police superintendent Sin Kwok-ming was quoted as saying. South Porcelain Morning post.

An initial autopsy concluded that he likely suffered trauma from a hard object and subsequently drowned, the outlet reported.

Investigators said the victim arrived at the park with the suspect around 11 p.m. Sunday in a taxi.

They went to the top of the waterfall where, about half an hour later, the man abruptly left, again by taxi.

Police are waiting for a toxicology report to determine drug use, the police said. South China Morning Post.

Sin said police were suspicious of the man because of his behavior. “A lot of things about him were unreasonable,” the newspaper quoted him as saying. Hong Kong Free Press. He explained that the man did not report the incident or stay in Hong Kong and that “some evidence had also disappeared for no reason.”

“All these circumstances suggest that this is not a case of natural death,” the superintendent said. The couple remains in custody while police conduct their investigation.
