Authorities say a man who killed a Mississippi police officer was suspected of sexually assaulting a
9-year-old girl, and had been released from prison last year after violating his supervised release on a gun charge.
Rankin County District Attorney Michael Guest said Wednesday that Pearl police officers went to Carnell Gaines, Jr.'s, apartment to arrest him and serve a search warrant after the girl took a forensic exam.
Gaines and investigator Michael J. "Mike" Walter, 37, died in a shootout later Tuesday at Colony Park Apartments in Pearl, a city of about 25,000 people just east of Jackson.
Another officer was shot in the hand and leg and was in good condition at a hospital Wednesday. A third was injured in the forearm, but not from a bullet wound.
