Authorities are gathering dashboard-camera and body-camera video relating to the incident from the highway patrol and the Charlotte-Mecklenburg Police Department, which sent officers to the scene after the shooting, said Audria Bridges, a special agent with North Carolina's State Bureau of Investigation.
"Because at least 20 highway patrol officers responded, it is taking some time to get all videos related to (the) incident together," said Bridges, whose agency is investigating the shooting.
Baker and Bridges declined to answer CNN's questions about whether Harris was armed.
CNN sent emails Tuesday with further questions seeking clarification about the matter, but officials said to protect the integrity of an ongoing investigation, they could not comment.
