I hate to throw a wet blanket on all the "bs ticket" posters but the LEO did not have to see the accident nor have a witness in order to issue a careless driving ticket. The theory is that if you have a single car accident, you were doing something careless such as driving too fast for the road or weather conditions, you were distracted, you zigged when you should have zagged, or some other careless action. In this case they can say that if you had been going slower due to the slippery conditions, the darkness and the curve, you would have been able to stop for the deer without running off the road - especially since you said it was standing there and didn't just jump out in front of you. It will be a very difficult ticket to fight considering the resulting condition of the car. The reason it was careless driving instead of reckless driving is that there is no need for them to prove intent or specific actions, just that there was a preventable crash.
