Steven Pieper is a young man who was sentenced for the murder of his ex-girlfriend, Jenny-Lyn Watson in upstate New York. After dumping Watson's body, Pieper, 21, tried to cover up by texting a mutual friend of theirs, pretending to be Watson. Using the letters "GTG" apparently did him in. Police looked at Pieper's phone, which was left November 19, 2010, at Watson's home in the Syracuse suburb of Liverpool, and pored over records. That shorthand for "got to go" was a term used by Pieper, not Watson, the prosecutor said. The one page handwritten letter comes with an envelope and a polaroid taken during visitation.
