DALLAS - A Texas-sized fight over an empty lot between the church and the school has a winner this afternoon - one family.

In a place for final rest, those left behind find comfort and peace at a family graveside.

"They're buried here. This is where my family is," said Rebecca Fernandez, 15, of her family's burial spot.

Fernandez is helping another family find their certainty, just beyond the fence at the Catholic cemetery, near Love Field called Calvary Hill.

"It's something real. It's not like we're just going out to do a project so that we can get a grade," she said.

Bishop Dunne High School students are using the latest GPS technology to zero in on a mystery, more than 120 years old.

Once-hidden graves surfaced in a fight over the place they are concerned with.

"It was between the Dallas Independent School District and the Dallas diocese over this parcel of land," said Bob Rouse, general manager of the Calvary Hill Cemetery.

The district wanted to expand an adjacent campus.

But that was stopped by the Texas Supreme Court. The sacred land sparred from bulldozers, keeping history untouched for these students.

"They bring a machine out and they actually take images, layered images of the subsoil. I think they went all the way down to 12 feet," said Brad Baker, a teacher at Bishop Dunne.

Survey teams came out here using ground-penetrating radar to survey the entire area.

They came up with five specific zones and marked 52 individual graves.

"They found little things that look like coffins. So, today, we're going to mark the waypoints of where they believe the grades are," Fernandez said.

"Ultimately, after they're identified, we're going to mark them with permanent granite markers that will say something to the effect of 'known only to God," Rouse said.

As life moves on, this sacred place will not be passed-over or go unnoticed again.
