In one of the photos, Sierra is seen walking from the city’s Sirkeci Train Station to the Cankurtaran neighborhood, where her body was found.
Police say this camera footage is the last recording of Sierra before she went missing.
The body of Sierra, a New Yorker who went missing in İstanbul on Jan. 21, was found on Feb. 2 near the city walls located in Cankurtaran. She had reportedly been bludgeoned to death. The police, who launched a thorough investigation to find the murderer or murderers of the US tourist, found tissue samples under the nails of the dead woman during her autopsy.
Sierra, 33, came to İstanbul on Jan. 8. She stayed for 13 days in the basement-floor room of a small house on Kömürcü Zeynel St. in the backstreets of Beyoğlu. The mother of two contacted her family for the last time on Jan. 21, the day she was supposed to begin her journey home to New York. That was the last time they heard from her.
