He is the ex-fiancee of Lumen Pierce.
Owen is a man in his early 30s with light blonde hair. He wears glasses, as well as a blue-and-white button-up shirt over a white undershirt with brown khaki pants. Owen appears to be of average, muscular build.
Owen is still in love with Lumen even though their wedding day ended badly as that is when she decided to leave him and move to Miami.
Lumen mentions Owen a few times throughout the course of the season, regretting that she tried to get married without wanting to settle down into that kind of life. Before she knew it, she had left...moving on down to Miami where she was abducted (until rescued by Dexter Morgan). Owen later calls her, after having arrived in Miami in search of her...and arranges a meeting.
The two meet a local cafe, where he is concerned about her having possibly met someone else. She denies it and the two talk about their past and family. Eventually, he brings up that he wishes to go with her around the world with a pair of tickets he bought, pronouncing that he still loves her despite all that happened. He remains patient with her, giving her the option to tell him the next night her final decision...letting her go until that point. When she never arrives, Owen tears up her ticket and storms off...apparently leaving Miami to go around the world on his own.
