Listeners, if you told me I would create multiple standalone episodes where someone met a cruel and untimely end due to a hit and run accident, I would not have believed you.

Yet here we are, just over halfway through 2019, and we have another case covering a bizarre, unresolved death due to a hit and run accident.

The first hit and run story covered this summer took place in Traverse City. That was episode 116, released on January 1, 2019, the death of Kelly Boyce Herbert.

This week's case takes us to Midland, Michigan, a place that we've been before, the home of Dow Chemical.

It's December of 1991, just a couple of weeks before Christmas, and Gregory McRoberts is spending time with his fiancé, Amy, and their daughter, Tia, preparing for the holidays.

Amy and Greg began dating just two years earlier when she was 19 years old. Greg's fiancé is pregnant with their second child, and Amy finally remembers the last day that she had with Greg.

He was in good spirits. They'd spent the morning Christmas shopping, and while the couple was struggling financially, they were young and they were in love. The future seemed bright and full of promise.

And it was on that mild December Thursday that Greg was listening to music, a song by Ozzy Osborne, or perhaps a track from Ozzy's band, Black Sabbath.

He was in to the music and telling Amy about it, asking her to listen to the lyrics, The Rhythm. He was cheerful, upbeat.

A bit after 5 p.m., Greg left the home in Amy's car. He needed to buy cigarettes and make a phone call. The trailer that the family called home did not have a phone line, and this was a few years before the advent of affordable cellular technology.

While he was out, the car broke down. Greg was good with his hands, and he knew he could fix the vehicle, so he returned home on foot. He told Amy what happened, and that he would fix the car. He'd take care of it.

Greg collected some tools and left again, this time on his bicycle. It's worth mentioning that Greg did not have his own car, so he used Amy's vehicle, or more frequently, he used his bicycle to get around town.

He was known to ride his bike all over, even in cold weather. He used the bike to get two and from his job at the local Big Lots store.

Come with me to a mild December day in 1991, when 24-year-old Gregory McRoberts, a son, a father, and a partner, leaves the home he shares with his pregnant fiance, never to be seen alive again.

And listeners, if I can speak plainly, at the end of 1991, Greg McRoberts was working hard at getting his shit together.

Like a lot of guys in their early 20s, he made a couple of missteps along the way. Nothing serious, mind you, but he knew it was time to get right and plan for his future, and the future of his young family.

It wasn't about him anymore. There were other people to consider. Greg and Amy had a young daughter, and the couple was expecting a second child in the spring of 1992.

While they were going through what some might call a lean period, Greg was dedicated to Amy and their daughter, Tia.

He confided in his friends at work that he was excited about the arrival of a second child. He loved his family. He wanted to do right by them, to be the best partner, the best father, and the best man that he could be for those who counted on him.

His own family was a good example of love, support, and hard work. His parents, Richard and Deanna, had recently celebrated their 25th wedding anniversary, a happy marriage that produced four children, Pamela, Thomas, Mark, and Greg.

The McRoberts worked hard, his dad at the local service station, and in addition to keeping the home and raising four children, mom worked at a local restaurant.
