Police say Celina Okwuone hanged herself in her closet Thursday night.
The 5th grader was found by her parents just before midnight.
Police say she used a belt to wrap around her neck and she had wrapped the belt around the metal shelving. Her father tried to lift her up and her mother tore the shelving from the wall.
"She had a diary," officer Tom Nichols.
"There are entries in her diary where it indicated she was being bullied at school."
Police on Monday didn't elaborate in detail on the contents of the diary.
"In the diary she expressed some typical kid stuff, i.e., who she likes, who she doesn't like," Nichols said.
Nichols said at this time there does not appear to be a crime.
"We're investigating an 11-year-old who hung herself," Nichols said. "We have to make sure it is what it appears to be, a suicide."
Nichols didn't know when the girl began writing in her diary.
