Baltimore County police shot and killed 23-year-old Korryn Gaines in Randallstown, Maryland, on Sunday after a standoff with police negotiators in which they allege she pointed a gun at officers and threatened to kill them.

Gaines son, 5, was taken to the hospital and treated for gunshot wounds. He is expected to live. It is not clear whether police or Gaines fired the bullet that struck the child.

The Baltimore County Police Department said they are not sure if the officers involved were wearing body cameras at the time of the shooting; the department just began equipping officers with them last month.
