NEW YORK — Sawyer Sweeten, who played one of Ray Romano’s twin sons in the CBS comedy “Everybody Loves Raymond,” has died. He was 19.

Sweeten killed himself, his sister Madylin Sweeten, said in a statement. There were no other details. Madylin, and Sawyer’s twin brother Sullivan, all played the children in the sitcom’s fictional Barone family.

The hit comedy aired for nine seasons before ending in 2005. Sawyer Sweeten was a toddler when the series began.

In a statement Madylin, who is four years older than Sawyer, said the family was requesting privacy.

“We beg of you to reach out to the ones that you love,” she said. “Let them have no doubt of what they mean to you.”

The comedy tended to focus on the fractured family dynamics of the sportswriter character Romano played, his parents and brother. The children were rarely more than an afterthought in the plots.

Sawyer Sweeten’s other listed credits were a 2002 movie starring Randy Quaid, and appearing in one episode of the TV show “Even Stevens.” IMDB listed no credits after “Raymond” left the air.
