I'm sorry that happened.
Keep looking, most likely he isn't far but underneith or behind something. Rabbits aren't long distance runners, normally they sprint to the next cover and hide there. They are very good at that, Patience. Have someone sit and watch the area around dusk and dawn (times when rabbits are most active)
Being new to this place, I fear the chances of him coming back are not great, this place isn't any more familiar to him than any other, would be different if he had been there for a month or two. But open up the fence, and put his food there, If he's used to pellets make noises he might be used to, like stirring the pellets in the bowl ore shaking the box, then sit back and watch, or move the search farther out. .
A motion detector, wildlife camera or box trap are very useful items for catching escaped rabbits. he might come back because of the human presence, but not while you are around activly searching.
It might be worth a try to start the search some way out and close in with as many people you can muster.
Keep looking, if you see him do not scare him, stay calm, ignore him, don't try to catch him in the open at first sight without preparing, if it fails at the first attempt he'll be nervous, catching a nervous rabbit is dufficult. Try to herd him into a corner (not easy!), or into a weir made from fence, or better put a fence around his position before catching him.
Rabbits up to 3lbs can get through normal 2" chain link fence, but it can slow them down, or they don't try if someone is outdside. Provide a hiding spot like a cardboard box with multible entrance holes, or just a big board elevated half a foot or so, something to hide under.
Good luck.
