This cold case was featured on Unsolved mysteries in 1989. 62-year old Terri McClure was attending her son's wedding in Stateline, Nevada on Friday January 14th 1983. At about 10 PM, she left the casino where her son and his in-laws were celebrating the wedding. She said that she would drive straight to her house in Reno, about an hour's drive. The day after, on Saturday, Terri's son and his newlywed went to Reno to pay Terri a visit. When they didn't find her or her car at her house, they called the police. On Monday, Terri's body was found inside her car parked in the parking lot of a Carson City casino. She had been shot twice in the head. Her car was locked, and the keys were in the ignition. Terri's purse was missing, but her jewelry was still on her.
The police soon regarded the son, Timothy McClure, as the prime suspect. He had no solid alibi for most of Friday night. Tim claimed he had gambled alone at a slot machine between 10 PM and midnight. At midnight, his in-laws left the casino, and after that, he and his wife went to several other places to party. However, neither Tim nor his wife could name specific locations where they went.
Tim had made a phone call to Terri's credit card company to cancel her credit card. According to the credit card employee, he made that phone call on Friday, before Terri was murdered. Tim claims he made the call on Monday. The police also saw a possible motive for Tim to murder his mother. Six months before her murder, Terri had taken out an insurance on her life of $10,000. Tim would share this with his sister in the event of her death.
The police submitted their evidence to the DA, but they deemed it insufficient to arrest Tim and bring charges against him. In 1992, Tim was arrested after new clues emerged after a rerun of the Unsolved mysteries episode. This time, the DA dismissed the case with prejudice. This means that Tim can never be tried for the murder of his mother. 32 years have passed since Terri's murder, and her killer (Tim or someone else) is still out there somewhere.
