Why would an enthusiastic lover of wine turn off the A/C in his cellar, knowing that all his wine will be spoilt as a result? A man who is more in love with wine than with people. Wine meant more to that man than money, maybe more than life. And why didn't he call his insurance after? Why did he keep it a secret?
Of course it's not valid evidence that will stand up in court, but hey, it'a a crime show, and a very good one 😏
