At 5:37 p.m. on April 28, 2004, Bill McGuire called the gas company. He and his wife, Melanie, had just bought their first house. He transferred the account, then called two friends to tell them the good news. In the days that followed, people who knew how often Bill used his phone and BlackBerry would try to work out which messages had actually come from him. [1]

Bill was a computer analyst at a college in Newark. Melanie worked as a nurse in Morristown. They had two boys. Dr. Bradley Miller, a partner at the practice, testified that he and Melanie had been having an affair since 2002. Prosecutors would argue that Melanie wanted to leave her marriage without risking a fight over the children. They would need evidence of what happened after those calls. [1]

Bill’s car

Melanie told a detective Bill had assaulted her in an argument and walked out. She suggested he or his car might turn up in Atlantic City. Police did find his Nissan there. The motel’s grainy surveillance footage put it in the lot at 12:40 a.m. on April 30. Later, Melanie told Miller she had moved it there herself after finding it at a casino, then taken cabs. Police found no record of the fare they looked for. [1]

The glove compartment held a bottle of chloral hydrate. A pharmacy had filled the prescription the morning of the house closing in the name of a patient at Melanie’s practice. The patient said she’d never received it. Miller denied writing it. Prosecutors argued Melanie had used the sedative on Bill, though the toxicology reports found no evidence of drugs in his body.

What came out of the water

Three matching suitcases were recovered near the Chesapeake Bay Bridge-Tunnel in May. The medical examination established that Bill had been shot. Two days before the closing, Melanie had bought a .38-caliber Taurus revolver. The bullets were consistent with several makes, including Taurus. Investigators never recovered the gun, and extensive searches of the Woodbridge apartment yielded no trace evidence of a killing there. [1][2]

Someone helping with the move had kept the industrial garbage bags in which Melanie packed Bill’s clothes. Investigators compared those with bags recovered from the suitcases. State witnesses examined lines left in the manufacturing process and argued that the bags shared a source and production period. Sally Ginter, a polymer chemist for the defense, said the results failed to establish the claimed match. [1]

The jury’s two answers

In April 2007 the jury convicted Melanie of murder, a weapons offense, desecration of remains and perjury. It acquitted her on separate charges over anonymous communications pointing toward other suspects. The judge imposed life for murder and a consecutive five-year sentence for perjury. New Jersey’s Appellate Division upheld the verdict and sentence in 2011, including the decision to admit the disputed bag testimony. [1][2]

The state’s account of the route to Virginia and the precise sequence in the apartment depended on inference. The three calls after the closing sit at a different place in the record. They’re a few minutes when people could still hear directly from Bill, and two friends heard that he had a house. [1]
