Police Chief Joseph Bennett revealed these documents and recordings just hours before Civil Rights attorney Ben Crump and Mikayla's mother were supposed to meet with reporters.
The teen was found dead about a mile from her home in the woods on April 18.
Her death sparked outrage as many believed the police did not handle the investigation properly.
Mikayla's mother, Calvina Strothers, claimed that authorities were covering up the murder of her daughter. Stothers said her daughter had been bullied for being Black and gay.
Just hours before her death, officials said she was involved in a confrontation with other teens.
"If they had not have immediately made a conclusion regarding my child’s death and did a proper investigation, we wouldn’t be here,” Strothers stated at a vigil and rally for her daughter.
Police Chief Bennett ordered the release of the records due to "significant public inquiry."
“We are today releasing a number of records that have been requested by the public and approved for release,” Bennett said in the statement. “The Department has also met with District Attorney Marian Ryan’s Office to ensure the release of these records will not adversely affect the ongoing investigation.”
On Tuesday night, District Attorney Marian Ryan released a statement with an update on the cause of Miller's death.
"We have received notice that the Office of the Chief Medical Examiner has ruled that Mikayla Miller died by suicide," District Attorney Ryan stated. "We have been in conversation with her family’s attorney regarding this development."
The State Medical Examiner found that the cause of death was “asphyxia by hanging.”
This investigation remains ongoing.
