Reporting horses? do i have enough reasons and motive ot do it?

well iv posted a few questions on here already about these horses. The owner is being a real jerk to us. I found out he owns a large Business in they are really expensive and make a good profit. Well the Tornado hit April 27th and all his horses got loose. We have been trying to catch them for the past week. The sheriff has tried and a whole bunch of other people im the only one who has caught any. They are possibly sick from pesticides on the corn Field they are in and they are very skinny. One will have her foal any day now. The owner came off at first as being really nice when he came to see the first horse i was able to catch. But he called the horse a gelding and it was really a mare. I Said um... no i think its a mare? He put up quite an argument that both the flea bitten grays were geldings and brothers. I said no im looking at her right now one is a mare the other one is the gelding. Well he asked how were you able to catch her? I said i had a bucket of grain and she came right up. He said iv never fed my horses grain. I said well she is under weight why don't you? He said she doesn't need it he also said he doesn't feed hay, Trim there feet or worm them. I said well horses need all of these he said they don't. well when I caught 2 more horses he refused to come help me. And he also refused to tell me the name of his Business i don't think he wanted me to know he had enough money to take care of these horses and to hire some one to catch them for him. well they got away because i didn't have enough help. These horses feet rae so terrible i don't think any of them have been trimmed in several years if at all. One bay mare has a hoof split all the way up to the band and they are very long. The older horses are in very bad shape. They have never been lead around or broke to halter or trailer. We are reporting the owner because he stated he doesn't properly feed these horses or give them vet and farrier care. He also left them out in the open on another mans property and government state property for the past 41 days knowing he could have payed some one to professionally get these horses. Do you think these are good enough reasons to report this man? i don't think he is responsible enough to take care of these horses. The mare has had no care and is about to drop a foal in the middle of a corn field with pesticides all over it and he hasn't even came buy to help us catch them. He said he has tried in the past but no one could catch them. He clearly has no use for these horses. Before the tornado hit he didn't even have a proper fence up. A steep banked creek was all that was keeping them from entering the road.
