It is not clear whether McLean's seven-year-old brother Nasyr, who has Down's syndrome, was home.

You could tell it was real. You could see past the ankle, but there was no blood,' Bobby, a superintendent for a building overlooking where one of the body parts was found, told DNAInfo. 'It's creepy. It feels like some Freddy Kruger stuff. I don't like it at all, man.' Byrd was taken to the medical examiner to determine the cause of death, which came back with stabbing on Wednesday. The bags were found strewn near El Batey Borincano Garden, part of a quiet residential block that comprises two religious schools and a church.
