COLUMBIA, S.C. (AP) — Karen Fish knows her son had a lot of things in life that he loved, including his job as a Richland County sheriff's deputy. Knowing that has helped her cope with his suicide nearly two months ago.

"He was doing exactly what he wanted to be doing and wouldn't have had it any other way," Fish said of her son, Master Deputy Derek Fish. "I guess that's what I try to think of. It was too short of a time that we had him, but while he was here he was amazing and brought a lot of joy to other people, and he accomplished so many of his dreams in a very short period of time."
