Copper Theft, Vandalism Strike Jacksonville's Diamond Grove Cemetery

At Jacksonville's Diamond Grove Cemetery, someone reached into the community's most protected space: the graves and mausoleums where families return year after year to honor the dead. Between Feb. 28 and March 21, thieves removed copper downspouts from the cemetery's structures and stripped doors from the mausoleum, leaving behind additional damage that city investigators are still working to document.

The city of Jacksonville and Morgan County Crimestoppers went public with the investigation on March 27, appealing to anyone who spotted unusual activity near the 44-acre cemetery at 1601 S. Lincoln Ave. during that three-week window.

What the thieves likely pocketed amounts to a fraction of the true damage. Scrap copper fetched around $4 to $5 per pound in early 2026, meaning pulled downspouts might bring a few hundred dollars at most to a secondary metal market. Custom restoration of copper drainage systems on historic cemetery structures, however, is specialized work that can climb into the thousands before labor, materials, and mausoleum door fabrication are counted. For families with loved ones interred in the mausoleum, the breach carries a weight that no repair estimate fully captures.

Anyone with information is urged to call Morgan County Crimestoppers at 217-243-7300. All tips are completely anonymous, and callers may qualify for a cash reward if their information leads to an arrest or property recovery. Investigators are asking specifically about vehicles or individuals seen near Diamond Grove between Feb. 28 and March 21, and about anyone who recently offered to sell large quantities of copper or mausoleum doors. Scrap yard operators across the region are also considered key potential witnesses, as stolen architectural copper typically moves fast to secondary markets.

Cemetery staff at Diamond Grove can be reached at 217-479-4651. The cemetery, city-maintained since its founding, sits in the southwest corner of Jacksonville, directly south of Calvary Catholic Cemetery along South Lincoln Avenue.

Metal theft from burial grounds and public structures has recurred across west-central Illinois, with Brown County authorities also seeking public help in a separate rural cemetery theft investigation. Whether those cases connect to the Diamond Grove incident has not been confirmed, and city officials have not publicly indicated whether other Jacksonville-area sites reported similar losses during the same period. That question is worth pressing: if Diamond Grove was not the only target, the pattern changes the investigation considerably.
