Eleven-year-old Jodi Parrack was murdered more than six years ago.
On Tuesday morning, her mother, Jo Gilson, addressed the media. That came after police made an arrest in connection with the case.
Raymond McCann, 46, is facing perjury charges.
McCann was a reserve officer with the Constantine Police Department at the time Jodi was killed, and he was suspended immediately after.
According to court documents, he has been a 'person of interest' in the case since the beginning.
The affidavit claims McCann acted suspiciously the night of Jodi's murder and lied to police about what he was doing during that time.
Court papers say police became suspicious after McCann suggested to four people to check the cemetery for Jodi after she disappeared.
Jo Gilson and her friend Julie McCann talked about the arrest on Tuesday. Julie has been married to Raymond McCann's brother for 20 years.
"It’s kind of bittersweet because everybody that loves Jodi is glad that the case is moving forward," Gilson began, "but most of the McCann family is like family to us, so both families are suffering for both people involved."
McCann is not being called a suspect in Jodi's murder, but police are hoping his arrest will help answer lingering questions about the case.
She also thanked detectives for their dedication to the case.
She says she tries to focus on the positives, like spending time with her granddaughter.
Jodi's body was found in a cemetery on November 8, 2007, and her bike was found nearby. She had been strangled.
Her mom found her body.
