According to his sister, Kali Raglin, Austin Majors, who played Theo Sipowicz in “NYPD Blue,” has passed away. He was 27.

“Austin Majors (Setmajer-Raglin) was a talented, wise, and compassionate person. Austin cherished and was extremely proud of his acting profession. He had never met a stranger since he was a young child, and his life’s mission was to make others happy “the family gave Fox News Digital a statement.

“He grew up in a small town where he loved camping and fishing with his family and Boy Scout Troop. He loved his dog, Sunny, and the horse he grew up riding, Balla. He graduated Salutatorian in High School while being an active Eagle Scout and member of the community. He went on to graduate from USC’s School of Cinematic Arts with a passion of directing and music producing.”

The statement continued, “Austin’s younger sister, Kali, says her fondest memories with Austin were growing up on set with him, volunteering at events with ‘Kids with a Cause’, and backpacking together. Austin was the kind of son, brother, grandson, and nephew that made us proud and we will miss him deeply forever.”

Majors passed away on Saturday, according to the Los Angeles County Medical Examiner-Coroner. The determination of the official cause of death has been “delayed pending further inquiry.”

Officials informed Raglin, according to Fox News Digital, that her brother’s death was “suspected fentanyl poisoning with an ongoing investigation.”

Majors appeared on seven seasons of the popular television show “NYPD Blue,” which led to his making multiple cameos on shows like “How I Met Your Mother,” “How I Met Jim,” “American Dad!” “Desperate Housewives,” “According to Jim,” and “American Dad!”

Raglin shared the tragic news of her older brother’s passing on Facebook on Sunday. “My big brother, Austin, is gone. He died last night. It’s so surreal to me still. He was only 27 with so much life left to live,” she captioned her post that included a slideshow of images of the two.
