Baltimore's police department was 'stunned' by the indictments in Freddie Gray's death

The Baltimore Police Department was still conducting its own investigation into the death of 25-year-old Freddie Gray when the state's attorney, Marilyn Mosby, announced charges against six officers, The Baltimore Sun reports.

Sun crime reporter Justin George was granted exclusive access to observe the department's task force investigation into Gray's death, which stemmed from a severe spinal cord injury sustained during a ride in a police van after he was arrested on April 12.

As of Friday morning, according to The Sun, police leadership was still planning on feeding additional reports to Mosby's office. The task force was expecting to continue working on its investigation through the weekend.

George describes the scene at the police station Friday morning, as task force members watched Mosby's press conference in Baltimore PD Col. Garnell Green's office:

They stood motionless as Mosby began speaking. A lieutenant wearing a suit and bow tie rested his left hand on a leather chair; Green stood in uniform against the wall, hands behind his back. As Mosby read off the charges - including second-degree depraved-heart murder, the most serious, against [van driver Officer Caesar R. Goodson, Jr.] - stunned looks crossed their faces ... They had not expected the state's attorney's office to act so soon.

As of Thursday, the day before the indictments against the six officers were announced, the task force had a checklist of 145 items to complete, The Sun reports. Their investigation is still ongoing.
