Hey everyone, and welcome back to Big Mad True Crime, where we get Big Mad over True Crime.

I'm your host, Heather Ashley, and today's case is out of Navinger, which is an extremely small town in north central Missouri.

0:14.8

Small talk sucks, so let's dive in.

Music Let's dive in. Kay Young wore a lot of hats. She was a dog breeder, a registered nurse, and a former school superintendent. She was also a mom and a serial bride. In 2004, 50-year-old Kay married her fourth husband, 41-year-old Bo Greasbauer, who was an Army National Guardsman and a father of three. The two settled into a

0:56.7

four-bedroom house that sat on Kay's families, nearly 100-acre farm in Navinger. The farm had a

barn and a few outbuildings and was Kay's pride and joy. Not long after they got married, Bo was deployed to Iraq for a year.

1:14.6

While he was gone, Kay ran the farm and bred dogs full time. Also, during that time, she got pretty

Bo went to work that day as usual, and Kathy came by the farm to visit Kay. She had plans to spend the

2:13.2

night. Bo finished his shift after midnight on what was now the 23rd and carpooled to a meeting spot closer to home.

2:21.2

At around 1.20 a.m., Kay picked him up and brought him back to the house.

2:26.1

But less than an hour later, at 201 a.m., Kathy called 911.

2:32.2

According to court documents, she told dispatch that she and Kay had found

2:36.8

43-year-old Boe near the front of the barn with, quote unquote, a big hole the size of his face
