ISTANBUL, Turkey — Turkish forensic teams searched the Saudi consulate in Istanbul overnight as the investigation into the disappearance and alleged murder of Saudi writer Jamal Khashoggi deepened.
Early Thursday, investigators wearing white forensic suits and blue gloves emerged from the building in an upscale neighborhood the the city. They loaded boxes and plastic and paper bags onto white vans.
Turkish Justice Minister Abdulhamit Gül later pledged that the investigation would shed light on what happened, adding that "whatever the international law requires will be done."
Gül told Turkish state news agency Andalou that the case was being investigated "thoroughly" and that the results of the investigation were expected "soon."
On Wednesday, Turkish forensic police followed Saudi investigators into the residence of the Saudi consul for the first time. The search by the Turkish team included the roof and the deployment of a drone over the area which is a ten minute walk from the consulate. Footage from the scene showed investigators using ultraviolet lights to look for stains.

The recordings were key to Turkey being confident enough to say that Khashoggi is dead and that Saudi Arabia killed him, according to both U.S. and Turkish officials, along with other individuals briefed on the intelligence.
Gruesome details in the alleged recordings have emerged. NBC News is not reporting the details of these accounts.
Turkish authorities claim Khashoggi was murdered by a 15-member Saudi hit squad who stayed in Turkey for only a brief period and then left. The Saudi government has denied and condemned the allegations.
Turkish officials revealed new information about members of the alleged Saudi hit team Wednesday, providing NBC News with scans of passports they say belonged to seven of the 15 Saudis who arrived in Istanbul ahead of Khashoggi's disappearance.
Turkish pro-government Sabah news site later published images of members of the alleged assassination squad reportedly taken at Turkish passport control on the day Khashoggi disappeared. The newspaper claims that the group then checked into two hotels and left the country later that day. None of this information has been verified by NBC News.
