DHAKA: The search for clues into where AirAsia Flight QZ8501 went into the sea continued Saturday morning, amid news that oil slicks had been spotted in the search zone.

The USS Sampson was one of the ships in the Java Sea looking for debris and bodies, the U.S. Navy said. On Friday, crew members helped recover remains, the U.S. 7th Fleet said.

In total, 30 bodies have been recovered from the wreckage of AirAsia Flight QZ8501, Indonesian officials said.

The CNN.com publishes the report on Saturday. 

What appears to be a piece of the fuselage was found, Singapore's Defense Ministry said. It resembles a window panel.

Indonesian search and rescue chief Bambang Sulistyo said oil was found in Karimata Strait.

"We saw oil slicks over there," he said, according to the state-run Antara news agency.

Finding the fuselage and the plane's "black boxes" are a priority. There are 59 teams of divers involved. That includes 22 from Russia, the country's Ministry of Emergency Situations said. Moscow also dispatched a search plane and a cargo jet.

Indonesian authorities have identified four of the recovered bodies. The first victim they identified, an Indonesian woman named Hayati Lutfiah Hamid, was buried Thursday. Many family members are waiting in Surabaya for news about their loved ones.

But with 162 people on the plane when it took off from Surabaya, Indonesia, crews have a long way to go.
