A West Phoenix neighborhood is on edge after a series of murders that remain unsolved. Five people killed in four separate shootings, the youngest victim being a 12-year-old.
Police now believe the crimes are all connected and they've increased patrols in the neighborhood.
Friday night a group of volunteers known as "Guardian Angels" took matters into their own hands.
"To the community, don't let this guy strike fear in the community. I know it's hard. It's easier said than done, but take away his power," said the chapter leader of 'Guardian Angels' Mike Upchurch.
The volunteer group "Guardian Angels" went door to door Friday night in Maryvale, passing out flyers in the area where five people, including a 12-year-old, were killed.
The suspect or suspects have not been caught.
"As long as we all work together as a community, 'Guardian Angels' and the people in the neighborhood, it does work. We were able to catch the serial shooters, the Baseline Killer, the Chandler rapist, the Southern rapist through these same methods along with other chapters in the states. These methods work," said Upchurch.
Police believe the same suspect or suspects are involved because of similarities of the crimes. The 4 incidents happened between April 1 and June 12, all happening on weekend nights in front of the victims homes in the area of 67th Avenue and McDowell to 55th Avenue and Campbell.
"To the serial killer, hey you're a coward. Flat out you're a coward. You're shooting innocent people. You killed a 12-year-old girl on a car in her driveway. What kind of person is that," said Upchurch.
Mike Upchurch with the "Guardian Angels" is hoping with their efforts along with the community's help the person responsible will soon be brought to justice.
"What they do on a daily basis, they take it away from you, they make you afraid of them and it empowers the serial killer. But if the killer knows the community is no longer afraid of him, you've taken his power away and we're trying to empower the community to take back the community from the serial killer."
