This story previously aired on Sept. 23, 2017.  Hal Wenal to investigator: To the best of my knowledge I will tell you everything I know. Hal Wenal to investigator: There are nights I wake up crying my heart out.  Middle of the night, like a child …it's horrible. It's really horrible. And especially if you don't know why.  Hal Wenal to investigator: Kay was a beautiful woman. …if you came out and I'd line up 30 guys I know, they'd all tell you the same thing.  Any guy would fall in love with Kay in a minute.   Hal Wenal to investigator: [Takes a deep breath] I have something in the back of my mind, I don't even want to say it yet, but that was years and years ago.  The weirdest thing was – and I don't even really like saying it is – her ex-husband. Investigator: Was she still married to him when you two met? Hal Wenal: He threatened her when she was trying to leave.  I know that. Hal Wenal to investigator: …and I said, "Well, what are you going to do?" And she said, "I told him we're not going."  She said, "He's livid about it." Hal Wenal:  I stand on that bridge on the second floor – I look down at that front door.  I say, "Kay, what happened here?  What really happened? Hal Wenal to investigator: I can say to you without reservation that I can't even think of anybody.  We have tenants occasionally who fall out, but they don't blame me.  Hal Wenal to investigator: If you don't make any money, you never get sued for anything.  The minute you make a buck, people come after you. I bet Kay Wenal never told anyone what she really was Hal Wenal to investigator: As God is my judge, I don't think Kay was having an affair or she had to be the best damn actress in the world. Hal Wenal to investigator: She was destroyed because she and Kay were like very, very tight.  I mean, extremely close.  Hal Wenal to investigator: I try to stay busy morning, noon, night.  I hate the mornings going to work 'cause I know I'm coming home to that house at night.  …Weekends, I despise.  Hal Wenal to investigator: I want nothing more on God's earth than to find the guy who did this. …and I'd give everything I have to get Kay's killer. 

Produced by Lisa Freed and Michelle Feuer Hal Wenal: When we met.  Absolutely.  Yes, she was. Investigator:  He loved her… Investigator:  Whoever did this … did this because of one of two reasons – they're very angry with her or they're very angry with you.  It turns out she was just a $ grubbing w----e!

At the time of her murder, Kay Wenal was married to real estate developer Hal Wenal – her fourth husband. He was smitten from the moment he first set eyes on Kay in a Reno airport. Hal Wenal:  But that's what she told me, so. Hal Wenal: I've been in this game for 40 years. Who the hell kills your wife? Not even the Mafia does that.  I loved her She said we could be together
