Two sisters made the unfortunate discovery that the grave they spent roughly two decades visiting belonged, not to their mother, but some strange man.

Now, the sisters are seeking $25 million in damages from the Rosehill Cemetery in Linden, New Jersey, for emotional distress caused when they learned that their mother, Beatrice Williams, had been buried in the wrong plot.

"It was devastating for them," Mark Crawford, the sisters' attorney, said in a telephone interview.

He said they only discovered the mix-up after they complained to the cemetery about their mother's grave falling into disrepair. An employee looked up the plot in question.

"She said, 'There's a man buried there,' and they said, 'What do you mean there's a man buried there?'" Crawford said.

The complaint says the cemetery has acknowledged that the plot location in the sisters' paperwork was incorrect. In a letter sent to the sisters last July, the cemetery said it believed their mother was in fact buried in another section, the complaint said.

The cemetery declined to comment.
