In 2003, Browne incorrectly told the parents of missing teen Shawn Hornbeck that their son was dead, and his body could be found somewhere near "two jagged boulders," according to her premonition.
She just meant figuratively dead.
And the "two jagged boulders" meant four years. A regular boulder would be a year, but a jagged boulder - TWO years.
So she was saying he was figuratively dead, but would be found alive after four years.
100% accurate.

Or mostly dead.
