I'm gonna kick someone's A** (rant)

I have a 7.5 month alaskan malamute puppy who has a large outside pen that he spends a few hrs in everyday(2-4). About a month ago he started howling after being put in there after 20 minutes. He would howl for 10 -15min stop for 30 start again etc. We have been working to get him to stop this (btw he howls in the house when left for awhile too) he's going through some seperation issuse, most of our imdeate neighbors have been very understand of the howl and it doesn't bother them.
Well we came home last night at 6:30 to find our puppy running lose(we left at3:30) in the front yard. We were shocked. he seemed ok but very freaked out. We went around back to find our gate open and continued to the pen to find that gate open as well. There are 2 dead bold locks on that pen and a latch on the gate it became obvious that someone had LET HIM OUT.
my first thought was possible one of my son's friends had stopped by heard the dog howl, and went to pet him and he got away. We checked the ans machine and our rear niegbor had called to tell us goku was loose in the back yard(both our yards are fenced in but we have no fence between us as our children play together) she tried to get him to come to her but she said he was acting spooked and wouldn't come near anyone. This was ast 4:45. She said she there weren't any kids around because her son was at his dads house for the weekend.
About 1/2 hr after we got our dog in he started vomiting what looked like beef stew and has continued to vomit during the night.
I know a neighbor up the street had her dog POISIONED last month and had to be put down.The neighborhood thinks it is an older gentleman who is alawys complaining about dog noise and kid noise and has threatened to poison peoples dog's in the past if they "dont shut them up" I called the police last night and they said there isn't much they can do since noone saw anything.
I'm taking goku to the vet to have hime checked out and hopefully he just got into somebad grub while loose and noone has hurt him. If i find the person that let him out i'm gonna have to kick his/her a**. in the meantime i'm going today to buy a padlock for my gate. I'm really pissed . We don't even lock our doors in this neighborhood.
Has anyone ever encountered anything like this and any ideas what to do or who to call? I mean if you want total peace and quite 24/7 move out to the country.
