According to Klaus Hamberger, this story can be found in:
“Der Europäischen Niemand” vol.XI, Leipzig, 1719.

This, more or less, is what is supposed to have happened:

“In the town of Lublov, a man called Michael Caspareck had died. His coffin, covered with red silk, was buried on 20 February 1718. Soon the dead man was seen again, going around and talking to people. He even sat down with them to have a meal or a drink. Then one day he showed up at a wedding and told the wedding-guests that he wanted to eat fish. But they would not let him in and locked the doors. But the dead man banged on the doors and threatened to do horrible things so they let him in. When they refused to give him a drink, he got angry and smashed all the drinking glasses. When they had given him a drink and brought him some fish to eat, he climbed back on his horse and disappeared. He also went to see his widow and managed to make her pregnant. He did the same to four other women. After Sunday Jubilate (the 3rd Sunday after Eastern) he wasn’t seen for 3 weeks. During this period he had gone to Warsaw to take care of some financial business. On the 26th of April, they opened up his grave and decapitated and cremated his body. But the dead man came back again and set fire to several houses. One time when he visited his widow, she asked him why he would not stay in his grave. He told her that he wasn’t welcome in heaven nor hell, because at his cremation they had burnt someone else’s heart instead of his own. Therefore he had to stay in the world for seven more years.

I tried doing some extra research on this to give you more details, but I`m sorry to say that all the articles I was able to locate are in german and I have no knowledge of that language.
I don`t trust Google Translate enough to make an article based on anything I might get off it…
I reproduced the original article from ShroudEater 🙂
