The suspect detained yesterday in the murder of Sarai Sierra has confessed, police say. Ziya T., whom the New York Post describes as a transient, says he "had sniffed a lot of glue" and then hit Sierra, a tourist from New York, "with something heavy. I came back in the morning and she was dead." Police released a 30-second video clip of his confession, in which he also says he doesn't remember much of the incident. Authorities say Sierra died after being hit in the head with a brick.
