SPARTANBURG, S.C. -- A school groundskeeper found a woman's body on the school's property Friday afternoon.

Authorities identified the deceased late Friday as Lindelle Robinson, 56, who lived on Miller Line, a street behind the Spartanburg Day School. Authorities said she had multiple health issues.

Robinson's body found in the back end of the property in an athletic field owned by Spartanburg Day School, according to sheriff's deputies.

School officials said that even though the body was not covered and was lying in an open area, it was in a location that would not have been visible to any of the students.

Sheriff's investigators are following standard procedures and will treat the death as a homicide until they determine otherwise.

The school's headmaster, Chris Dorrance, sent the following note home to parents:

"Early this afternoon a member of our grounds keeping staff discovered a body on the back corner of our campus. Little is known at this time about the circumstances. The police are currently investigating and have not released any specific details about this person.

"Classes have continued as usual and students have been kept from the back half of campus. Students have not been at any risk and appropriate security measures are in effect. If necessary, we will notify you of any additional information as it becomes available to us."

Spartanburg Day School has lower, middle schools with a total student body of about 500.
