How do I repair a crack in a brick windowsill? I assume that it needs to be sealed to prevent water from getting in, especially during the winter when it could freeze.
The other side of the window has a similar crack that was repaired by the previous owner of our house.
It appears they may have used some sort of epoxy. Is that what I should do for the other side as well? If so where do I get it and how do I use it?

If the cracked bricks are loose (as in when you wiggle them they move) they should be removed and new brick installed (or clean the old ones of mortar).
If the cracked bricks are sound and secure the gaps should be filled ,as you noted, to keep water from further damaging the sill.
There are many colors of concrete-type caulking, so if desired the gaps can be filled with a red color and the joint with a grey color. Use a urethane caulk for greater longevity.
A two part epoxy would work just as well as a caulk but it would be difficult to color match (if that is important). Epoxies can be purchased at a local hardware store or a contractors warehouse.
