'Pawn Stars' Frontman Rick Harrison's Son's Cause Of Death Revealed

The frontman of "Pawn Stars," Rick Harrison's son, Adam, passed away at age 39. Adam reportedly died while in Las Vegas.

Unlike his two siblings, Adam was not very involved with his father's show or store and led a more private life. Harrison has since spoken out about his son's death, expressing how heartbroken he is by the loss.

According to a report, Harrison's son, Adam, passed away on Friday while in Las Vegas. A rep for the TV personality revealed that the 39-year-old died of an overdose. At the moment, it's unclear what substance Adam overdosed on.

In a statement, the family said of his death: "Our family is extremely saddened by the death of Adam. We ask for privacy as we grieve his loss."

Harrison broke his silence on Adam's passing with a heartbreaking post on social media. "You will always be in my heart!" Harrison wrote along with a broken heart emoji. "I love you, Adam."

The short tribute was accompanied by a photo of him smiling beside his son in a bar.

Adam is one of Harrison's three sons. Unlike his brothers, he was not hugely associated with his father's show. Harrison shared his late son and his elder brother, Corey, with his former wife, Kim. The TV personality had his other son, Jake, with his second wife, Tracy.

For fifteen years, "Pawn Stars" has followed the Harrison employees at their Vegas Gold & Silver Pawn Shop as they authenticate items brought into their store and make offers to their sellers.

Adam was allegedly employed at Gold & Silver Pawn before the 2009 launch of the show. But he hasn't been employed there lately.

Following news of his death, tributes poured in for Adam from celebrities and fans of his father.

Donald J. Trump Jr. wrote, "I’m so sorry man," while actor Christopher Clawson said, "Condolences Rick. The fentanyl situation is out of control in this country and nobody seems to be doing anything meaningful about it. Use your platform to help change that."

A fan commented, "No, no, I can't believe it; they just broke the news here in Chile. I'm very sorry. God give peace to your hearts, a big hug for you, and your family."

Another fan wrote, "I am so sorry for your loss, Rick. Too many of our children are taken by the disease of addiction."

A fourth person stated, "I am so incredibly sorry. God bless you and your family. I know you don’t know anyone here in these comments and it doesn’t really matter, but there’s an entire legion of people that have been impacted by your family and those close to you, Adam included. I hope you guys can find solace in this time."

One more individual noted, "My condolences, we are going to be with our sons one day just be strong and peace for you and Family God blessings."

Rest in peace, Adam Harrison.
