A TV journalist was killed and a crew member was injured while they were covering an earlier shooting incident in Orange County, Florida, on Wednesday, police said.
The big picture: Police said they arrested Keith Melvin Moses, 19, and charged him with murder in connection to the first shooting Wednesday morning. He's expected to be charged over the later shootings of the TV crew and also a mother and her 9-year-old daughter, who died of her injuries.
