The suspect could've "easily taken vehicles, taken money, credit cards, but none of that stuff has been taken," he said. "It seems that this person or persons is very focused on the killing -- and very calm and confident afterwards."

All of the victims were alone, police said, and the killings happened at night or in the early morning.

"What we seem to have in common is probably complexion -- it has been folks that are different races, but they have a similar complexion," the chief continued. "The location, the environments have been consistent: It's very dark locations, it's locations where there's not very many witnesses around."

"This is a person that lurks in the shadows," McFadden added. "Our victims are being caught by surprise."
