Authorities in Papua New Guinea are investigating the murder of a woman whose body was found at the home of acting Prime Minister Sam Abal in the capital of Port Moresby.

In a statement carried by local news outlets, Mr. Abal says “all family members living with me are immediate suspects” and pledges to cooperate with police.

Police Commissioner Anthony Wagambie says investigators are searching for Mr. Abal's son, who was seen entering the compound with a female companion early Monday morning.

The incident comes during a politically sensitive time for the small Pacific island nation. Mr. Abal recently took over while 75-year-old Prime Minister Michael Somare, Papua New Guinea's founding leader, recovers from heart surgery in Singapore.
