Court documents released Friday revealed that 19-year-old Mikaela Conley was beaten and strangled.

The affidavit, which had been sealed, stated that Conley, who was found dead on June 2, died of blunt force trauma and strangulation.

Jalique Keene, a 21-year-old former classmate of Conley's at MDI High School, is charged with her murder.

The affidavit also confirms the existence of a security video from outside the Conners Emerson School that shows Keene carrying Conley away in the direction where her body was found.

Keene is being held without bail at Hancock County Jail.
