Need to relocate to a safer place

https://www.fox10phoenix.com/news/mesa-family-traumatized-man-kills-dog-before-shooting-himself-devastating 
Our hearts are completely broken.  We lost our best friend in a horrific and unprovoked attack, our beloved dog Bailey.  A man we do not know approached my wife in our front yard.. When I came out to see what was going on he pulled a gun from his car and headed straight for us. We ran for our door and when we opened it our dog ran out and he shot Bailey in the head.  The bullet went through her brain and shattered her leg.  We witnessed all of this.  We had to put our family dog down.  Our entire family is emotionally damaged.  The man then ran off and shot himself dead - why, we'll never know.  We are traumatized and no longer feel safe living in our home.  We have 3 little ones ages 7, 4 and 3 months.  Please help - we desperately need to move to a safe environment where we can start over.  This horrible event could've been more tragic if not for Bailey.  Anything will help.  Thank you for taking the time to read our story.
