Several tombstones have been uncovered in the backyard of a Roseville home.
Police said a homeowner was digging for a patio in his yard on Tuesday and found 10 to 12 tombstones.
The dates of death range from the 1950s to the 1980s.
Police said they are reaching out to area cemeteries to see if they are missing any tombstones.
"They dug down several inches, 8 to 10 inches, struck these stones. They were laying facing down," said Donald Glandon, Roseville assistant police chief.
The stones were used by a previous homeowner to make a walkway or path. They either sank in the soil or were covered up.
"These were replaced stones. Basically a grandfather, grandmother passed away and when the other grandparent passed they replaced the original single stone with a double stone," said Glandon.
Glandon believes the stones belong to Mt. Olivet Cemetery where some of them were removed legally.
Anyone who recognizes any of them or has more information is asked to call Roseville police at 586-447-4483.
