According to the news, Turkish police were unsure about ______.

The family of Sarai Sierra, an American woman who went missing in Istanbul nearly two weeks ago, is in mourning after learning that Turkish police found her body Saturday. Turkish police found the woman’s body near ancient stone walls in Istanbul’s Sarayburnu district. Police suspected she had been killed at another location. Police told CNN’s sister network CNN Turk that the body of the 33-year-old mother of two showed signs of stab wounds. However, the police chief of Istanbul, Huseyin Capkin, said Sierra died from a blow to her head. Nine suspects had been detained in connection with the woman’s disappearance and death. Sierra’s family and friends first sounded the alarm last week after she did not arrive on a return flight from Istanbul on January 22.
