He was best known for playing Kip "Half-Sack" Epps in the first two seasons of the FX series Sons of Anarchy, and for other television roles such as Gilby in The Sausage Factory (2001–2002), Pearce Chase in Quintuplets (2004–2005) and Dennis "Chili" Childress in The O.C.

[3] Lewis began making television appearances while in his late teens, with guest starring roles in Boston Public (2000), The Guardian (2001) and American Dreams (2002), among others.

He co-starred as Pearce Chase, one of five siblings on the Fox series Quintuplets, and appeared in the movie Raise Your Voice (2004) alongside Hilary Duff.

Police were called by neighbors after Lewis violently attacked two people at the property next door, and Davis was heard screaming.

Officers from the Los Angeles Police Department (LAPD) found Lewis' body on the home's driveway.

[9][10][11][12] His death was investigated as a homicide, and it was later determined that he had killed Davis by manual strangulation and blunt force trauma to her head.

[13] Lewis' family has spoken out about his history of untreated head trauma, leading some to speculate that he developed a psychological disorder, which led to his sudden spurts of violence.

[3] Sons of Anarchy creator Kurt Sutter tweeted about his death: "It was a tragic end for an extremely talented guy, who unfortunately had lost his way.
