Philippine police have filed murder charges against the owner and crew of a passenger ferry that capsized, killing 59 people, an official says.

The charges were filed late on Friday in the central city of Ormoc over the sinking of the Kim Nirvana, regional police chief Asher Dolina said.

An initial police investigation and interviews with survivors indicated the vessel abruptly turned in waters off the central port of Ormoc on Thursday, causing it to capsize, Dolina said on Saturday.

“They were not careful, showing there was an intent to kill. They were reckless on purpose,” Dolina said.

A total of 19 people were charged, including ship operator Joge Bong Zarco, captain Warren Oliviero and all 17 crew members, Dolina said.

All members of the crew survived and are now in police custody.

Murder is punishable by up to 40 years’ jail under Philippine law.

The police investigation is separate from a coast guard inquiry, which will primarily determine the cause of the mishap.

However, the coast guard may also recommend criminal and administrative charges.

“We filed the charges as soon as we could because we don’t want the suspects to leave the country,” Dolina said.

The death toll stood at 59, transportation secretary Joseph Emilio Abaya told ANC television on Saturday.

This toll was higher than the 45 reported by the coast guard, which was based on the ship’s passenger list. The coast guard and other reports have put the number of survivors at 142.

The coast guard earlier said the 33-tonne ship could carry 194 people, including 178 passengers and 16 crew, but the ship was carrying at least 198, according to the casualty count of Ormoc’s city council.

Overloading of cargo and passengers might have been to blame for the disaster, Ormoc city councillor Godiardo Ebcas told AFP.

Survivors reported seeing up to 150 sacks of cement and more of rice and fertiliser in the ship’s cargo area before it capsized in relatively calm seas, he said.

Passengers on the ferry’s route from Ormoc to the Camotes islands regularly bring supplies from the city to their remote fishing villages.

Search operations with rescue divers were stopped on Friday before the ship was lifted to the port’s berthing area.

Bloated bodies spilled out of the Kim Nirvana’s wooden hull as a crane lifted it from the water and placed it at Ormoc port, Ebcas said.
