At least 14 deaths in Arizona are blamed on two deadly crime sprees by serial attackers dubbed the "Serial Shooter" and "Baseline Killer" over the past year.
The Arizona Republic said U.S., state and local law enforcement officers, acting on tips, arrested two men in connection with the "Serial Shooter" crimes at a gated apartment complex in Mesa, Ariz., after a 22-year-old woman was killed Sunday night while walking.
"They are the serial shooters that this task force has been hunting," Phoenix Police Chief Jack Harris told a news conference Friday.
"These are two monsters we have been hunting, and I promise you and our colleagues promise you, we are not finished," said Phoenix Mayor Phil Gordon.
The series of shootings, which began in May 2005, has left six people dead and 18 wounded.
Meanwhile, investigators sought the "Baseline Killer" believed responsible for eight deaths in the state since August.
