The entertainment industry lost another talent with the passing of actress DuShon Monique Brown.

She died shortly after noon Friday at St. James Olympia Hospital in Illinois, Chicago, according to Robert Schroeder, Brown's representative.

Brown's last role was on the hit NBC show Chicago Fire, in which she portrayed Connie, the no-nonsense assistant to Chief Boden. Prior to joining the show in 2012, she had roles in Shameless, Empire, and Prison Break from 2005 to 2007.

"We are devastated by the loss of a very talented and kindhearted soul," Schroeder said in a statement. "DuShon was a film, television, commercial and voice-over actress who also graced the stages of many Chicago theaters. She brought laughter and joy to many and will be greatly missed."

Chicago Fire producer Dick Wolf also issued a moving statement following the actress's death.

"The Chicago Fire family is devastated to lose one of its own," he said. "Our thoughts and prayers are with DuShon's family and we will all miss her."

Wolf's sentiments were echoed by some of the other cast and crew members, including Jesse Spencer and Derek Haas. Brown, who was a mother of one, was regarded as a maternal figure by her colleagues.

"Our beautiful Dushon Monique Brown passed away on Friday. You will be sorely missed by your family and ourselves," tweeted Spencer. "Thanks for all the great laughs we had. Love."

"Very sad to hear about DuShon's passing yesterday.  I'm grateful we got to work with her and so happy she got to make millions of people smile," Haas wrote. "She will be greatly missed."

Schroeder told media outlets that Brown died of natural causes. TMZ reported that the actress had previously shown signs of an illness, but the symptoms weren't treated and her condition escalated.

According to the celebrity news site, those who worked closely with Brown revealed that she complained of chest pain in the days leading up to her death, and even admitted herself to a Chicago hospital.

After running tests, which came back clear, doctors sent Brown home.

Unfortunately, on Friday, her condition worsened and her family had to call in the paramedics. She was transported to the hospital where she later died.

Brown's experience sounds awfully familiar with stories that have recently surfaced about patients who have been cleared to go home but end up dying shortly after.

A number of people have either died or come close after their illnesses were misdiagnosed by doctors. Last week, it was revealed that a 13-year-old boy died from a sinus infection that spread to his brain days after he was sent home from the ER twice.

Before that, a five-year-old girl and a newborn also lost their lives after they were turned away from the hospital.

As for Brown, it is suspected that her unexpected death was due to a heart attack, though an official ruling for cause of death is yet to be made by the medical examiner.

Brown is survived by her fiancé and 14-year-old daughter, Zoe.

Brian Zvonecek, Brown's co-star, has set up a GoFundMe page to help cover some of the funeral expenses as well as other miscellaneous costs that her family might incur.

"Despite her visibility and involvement in a television show, DuShon's full time job was as a Chicago Public School's counselor, " wrote Zvonecek. "Please join us in offering DuShon and family support during this very difficult time. Your generosity will help fund the cost of funeral arrangements and other financial burdens that her family must shoulder."

In a little over 24 hours, the campaign has raised over $8,000 of its $10,000 goal.

In addition to the episodes of Chicago Fire she already filmed, Brown will posthumously star in a TV movie titled Public Housing Unit, which is set to premiere later in this year.

Our thoughts and prayers are with Brown's family during this extremely difficult time. May she rest in peace.
