"We thought it was a perfect marriage." Coming from their closest friends, these words may have been the ultimate compliment for Woodbridge Township, New Jersey couple William or Bill and Melanie McGuire. They were a lovely pair blessed with two beautiful boys and stable careers. But life can spring an unexpected surprise, and it was an alleged infidelity in the McGuires' case that shattered to tragic pieces their marriage with the gruesome death of Bill in 2004. There was no direct evidence, no eyewitness, but a great deal of circumstances that were amassed implicated Melanie as the perpetrator. She became the infamous "Suitcase Killer" in the sensational "Suitcase Murder."
