Police has launched a manhunt for a jealous man, who used a hammer to murder his stepdaughter in Bangkok, Thailand.

Kannayao police found 29-year-old Nanthachaya “Noon” Janmokha with her head bashed in in a second-floor bedroom of a three-storey townhouse in Ram Inthra Soi 109. She was seven months pregnant. The unborn child died too. A bloodstained hammer was found near the body.

Thanawat, 29, the husband of the deceased gave evidence to the police at the scene. He said that the man responsible was Phoomjai, 57, a motorcycle taxi rider in the soi known as “Jai”.

Thanawat – a salon owner in business with Pim, the mother of the victim – said that Jai and Pim were a couple. They had had a big argument. Jai was jealous that Pim spent time talking to an uncle of the victim.

Pim got so fed up with his jealousy that she left him and went to relatives outside Bangkok in Amnat Charoen, reported Sanook.

Jai called her up and said if she didn’t come back to him he would kill her daughter to teach her a lesson.

He then carried out that threat mercilessly hammering the pregnant stepdaughter to death.
