Narrative:

During the walk around after the inbound flight my first officer (first officer) noticed a static wick missing on the elevator. After calling maintenance it was determined it could not be deferred. Maintenance was called out and upon further inspection there was damage found on top of the elevator caused by a suspected lightning strike. Since the damage was on top of the elevator the only indication was the missing static wick. The weather on the day of operation was clear so it stands to reason the strike happened before we had accepted the aircraft. I flew 3 legs before the damage was found. My first first officer on the first turn missed the damage and during the third walk around is when my second first officer noticed the missing wick.the event occurred before we had accepted the aircraft but we failed to notice the missing wick as well. When the strike occurred is unknown. Wick wasn't found to be missing until my second first officer found it. A more thorough walk around is the only way to prevent this from occurring again. It's obvious that my 2 first officer's weren't the first two to miss it since the strike had to happen sometime during the previous days. My second first officer found the problem and although he didn't find it on the first leg he did come across the damage and reported it to me once it was noticed. I'm certain that this has taught him a valuable lesson as it has me and for it we will be far more detailed in the future.
