Phoenix's Serial Shooter Strikes Again

Phoenix police have added another shooting to the lengthy list attributed to an alleged serial killer apparently targeting people at random. Authorities now believe a man who opened fire on a vehicle last month is the same one responsible for at least eight other shootings since March, resulting in seven deaths, reports the Arizona Republic, which breaks down each incident. In the most recent case, police say a 21-year-old man and a 4-year-old boy were inside a vehicle in a residential neighborhood on the evening of July 11 when a man opened fire, then fled in a dark BMW, per ABC 15. Neither occupant was injured.

"The threat is still alive," but "if there can be a benefit to something like this, it's that we did obtain additional evidence," a police rep tells NBC News. Like in other cases, there appears to have been "no apparent motive, no pre-incident contact," he says, per CNN, adding physical evidence also links the case to the serial shooter. He's described as a white or light-skinned Hispanic man in his 20s and police believe he has access to several vehicles, including a white Cadillac or Lincoln and a black 5 Series BMW. The reward for information leading to an arrest has just been raised to $50,000. (Read more on the shooter here.)
