This led investigators to believe the dead body of the insider-turned-critic of the Riyadh regime was disposed of through the drains as liquid, the paper said.
Khashoggi was last seen entering the consulate on October 2 to obtain documents for his forthcoming marriage. His body has never been found.
After repeated denials, Saudi Arabia finally admitted the 59-year-old had been murdered at the mission in a "rogue" operation.
However, Turkish President Recep Tayyip Erdogan has accused the "highest levels" of the Saudi government of ordering the hit, while some officials have pointed the finger at the all-powerful Crown Prince Mohammed bin Salman.
Yasin Aktay, an advisor to Erdogan, suggested last week the body may have been dissolved in acid.
Khashoggi's Turkish fiancee Hatice Cengiz took to Twitter on Thursday writing, "I'm unable to express my sorrow to hear about dissolving your body Jamal!" They killed you and chopped up your body, depriving me and your family of conducting your funeral prayer and burying you in Madinah as wished."
A Turkish official this week confirmed a Sabah report that chemicals expert Ahmad Abdulaziz al-Janobi and toxicology expert Khaled Yahya al-Zahrani were among a team sent from Saudi amid investigations into the murder.
