Authorities in Mississippi are investigating whether an unidentified body is that of a missing 60-year-old woman.

News outlets report someone located a female body Saturday near the Homochitto National Forest. Lincoln County Sheriff Steve Rushing says it appears the body had been there for several days.

A son of Dianne Richardson McMorris called the sheriff’s office Sunday after hearing about the body. He told authorities that family members hadn’t seen McMorris since Aug. 19.

Rushing says investigators are exploring all avenues to determine whether the cases are connected. He says a Silver Alert wasn’t issued when McMorris was reported missing because she doesn’t have a medical condition that would impair her judgment.

The Mississippi State Crime Lab will conduct an autopsy. Results are expected by next week.
