New evidence has been discovered in the 1989 murder trial of Eric and Lyle Menendez. The brothers were convicted of killing their parents, but now, a handwriting expert claims that a note found at the crime scene was not written by either suspect. The note, which contained a confession, was previously dismissed due to doubts about its authenticity. The new evidence could potentially lead to a retrial or even exoneration for the Menendez brothers.
