Phoenix police are investigating another series of random shootings but aren't yet declaring them the work of a third serial criminal.
The most recent victims were hit early Saturday morning about 20 minutes apart. No one has been killed, but some of the victims have suffered serious injuries.
The assailant or assailants are driving around in a vehicle between 10 p.m. and 3 a.m. shooting men and women.
There have been 13 victims since May 2. Most were out walking. But one victim was riding a bicycle and another was sitting in a parking lot. Ashley Armenta, 27, was struck in the back of the head at 2:38 a.m. Saturday at 44th Street and Devonshire Avenue. At 3 a.m. Gary Begay, 31, was walking in the 5000 block of East Van Buren Street when he was shot in the torso.
Police have no suspect and vehicle information to release to the public.
"We have no idea who the suspect is," Sgt. Andy Hill said. "We're calling it a series of possibly related shootings."
Investigators consider these 13 shootings possibly related by method and physical evidence that is not being released, Hill said.
There is no evidence to connect this series of shootings to two other sets of high-profile crimes being investigated in Phoenix.
Police continue to hunt for the Baseline Rapist, a serial killer who is responsible for 19 crimes since Aug. 6. The crimes include sexual assaults, robberies, kidnappings and homicides. Thus far, only the five homicides have been connected by evidence, Hill said.
The man last struck June 29 when he killed a 37-year-old mother at a car wash at 2924 E. Thomas Road.
Police also seek the person or persons responsible for crimes that began with the shooting of animals and escalated to random people. These shootings started May 30, 2005, and four people have been slain.
Anyone with information about the crimes should call Silent Witness at (480) 948-6377.
