Miyonna was reported missing on November 2, and the police department arrested her half-brother, 25-year-old Jahreese Jones of Wilmington, less than a week later. His girlfriend, Randi Johnson, was charged with obstruction of justice.
District Attorney Ben David said he expects to bring further charges, including murder charges.
"They have our commitment that we are going to do everything we can to make sure that she gets justice. And our condolences and prayers are with that entire family and her friends, and we know she has many," David said.
Law enforcement found Miyonna's body in Pender County, but David and Wilmington Police Department Chief Donny Williams wouldn’t provide further information about where, other than to say it was, “up there.”
Further information will come out in the trial, David said.
Williams thanked all those involved in the search, and noted the toll the case had taken on those involved.
“This case has taken a mental toll on our personnel and for others directly involved. We will be following departmental protocol and referring all of our people for mental health follow-ups," Williams said.
Williams noted that WPD worked with a host of other agencies, including the Wilmington Fire Department, New Hanover County Sheriff’s Office, New Hanover County Environmental Management, Brunswick County Search and Rescue, Pender County Sheriff's Office, and the CUE Center for Missing Persons.
