How can I get local law enforcement more involved (to care at all) about animal abuse and neglect?

I work with a restarting humane ociation in a county that hasn't had one in 17 years.. we badly need all the help we can get, as the Abuse/Neglect chairperson I have been getting more and more calls monthly concerning these cases, because the ociation is so new the local law enforcement has jurisdiction for animal cases, meaning we can't go in an get an animal in a dangerous situation, or give the owner notices/fines etc.. so basically I receive abuse cases and collect as much information as possible and take pictures if possible without tresping, and then p this information to the police/sheriff department depending on where the animals' location is.. My problem is that the majority of the deputies I've been dealing with just don't care.. for example I handed him a case of two horses in an abandoned lot, owner hasn't been their in a long time, neighbors claim the horses aren't theirs and therefore won't feed them, in the meantime these horses are starving, this was a week and a half ago... the deputy I spoke with went off for a week for training and I'm not sure if the department is just avoiding me because they feel it's not important but basically I keep calling and they keep telling me he's not available and they'll put a post it note on his door to call me. ..or I leave a voice mail and never get a call back...I don't even know if he's been out to look at the horses... and we told law enforcement we had someplace for the horses to go, we just need to legally obtain the horses. ... does anyone have any ideas for ways to get the law enforcement to care more about these animal cases? I've thought about writing an article in the paper, posters, etc.. but I need to do something. I'm also attempting to make an appointment to meet face to face for a few minutes and ask them what I can do to help them, and to stress that I just want a follow up phone call to let the ociation know what happened with these cases as well as to actually help the animals not let them die. I need a brainstorming session. There are some officers I've worked with that care, but some others... it's like they'd rather shoot the animal instead of help it.. or just let it die of a slow starvation
