People living near the crime scenes where a serial killer or killers have struck say fear is changing their lives.

We went from one neighborhood to another on Thursday, affected by the killer, and came across Holly Garcia, who would have been Diego Sanchez's mother-in-law, had he not been gunned down by the serial killer here in his front yard on April 1.

Underneath the family's mailbox, there's still a bullet hole.

In the front yard, there's a cross.

Both serve as a daily reminder: this serial killer is no joke.

“We don't want to come outside, 8 o'clock at night all my kids are in the house. If it starts getting dark, everybody used to be out here, we used to talk to each other; nobody's out here anymore,” said Garcia.

Despite real concerns over this west Phoenix serial killer, we caught up with Vern Sanders, as he was working on his truck in front of his house, just down the street from where the latest killings took place.

“When the sun goes down, that would be a definite concern. I'm definitely concerned; it is something to be concerned about,” Sanders said.

Sanders, though, says he's noticing the neighborhood stepping up, becoming one, keeping an eye out for each other, despite a language barrier among many.

“Us as neighbors, we weren't that close, but now we're coming together to talk and discuss this stuff and say if we see anything in this neighborhood that's unusual to report it,” said Sanders.

A little more than a month has passed since that last deadly shootings.

Garcia says she's on pins and needles, hoping no one else is killed.

“Just waiting for if something else happens and watching the news and praying that another person's life isn't taken,” said Garcia.

Several people, who did not want to talk on camera, told us shootings, violent robberies, things of that matter are the norm in their neighborhoods. They say they’re not as concerned as others may be about this serial killer.

Either way, just about everyone we spoke with told us they would call the police if they could put this whole thing to an end.
