SIBU: A woman and her six-year-old son were found dead in their double-storey house at Jalan Langsat here.
Police have identified her as Hung Yu Yuin, 34, and her son, David Ting Yu Soon.
Sibu OCPD Asst Comm Shafie Ismail said Hung was found hanging from the ceiling of the sitting room and Ting's body was found on the floor at about 7.50pm on Sunday.
He said the boy was believed to have died of strangulation as a piece of nylon string was found at the scene.
ACP Shafie said police were investigating the motive behind the deaths.
A police party rushed to the house after receiving a telephone call from Hung's neighbours as they heard someone screaming in the house.
Police had to break down the front door as it was locked from the inside.
Sources said Hung had earlier quarrelled with her husband over some matters, and that he was not around when the tragedy happened.
