Though several men were initially detained in connection with the murder of 33-year-old Sarai Sierra, whose bludgeoned body was found in Istanbul last month, Turkish police say they've now arrested a suspect identified as "Ziya T" and "Laz Ziya." The 46-year-old homeless man told a television reporter that he'd been sniffing paint thinner when Sierra was killed. "I do not remember how it happened. I must have hit her head with a heavy object," he said. "As I came back in the morning, she was dead. I covered her."
