Restaurant employees and other patrons recalled seeing Nick with the woman when questioned by police.

Nick had no alibi, as he was alone the remainder of the evening.
Nick had thought about cheating on his wife, Gina Dane being a very attractive woman, clearly interested in him. After second thoughts on how lucky he had been to have such a wife as he, and children, a job he enjoyed and everything in his life being near perfect, he decided not to take things further with Gina Dane, no matter what, the cost was too great.
But now Gina was dead. Found in her hotel room. Murdered they said. She must have come on to another man somewhere else. Or her date called and she met up with him.
All Nick knew was that he did not kill Gina Dane. He hoped his wife believed that. He hoped the world knew he wasn’t capable of murder.
Nick knew his luck was running out, that he would be arrested. He knew enough from watching a lot of crime shows on TV to call a lawyer and remain silent. He would be their only suspect.
