Following the sudden and tragic passing of Rick Harrison’s son, Adam, the “Pawn Stars” star broke his silence by posting a heartfelt tribute on Instagram. Adam, 39, died of an overdose in Las Vegas on Friday, leaving his family devastated.

“You will always be in my heart! I love you, Adam. 💔,” Rick wrote, sharing a photo of himself smiling with Adam at a bar.

A family representative, Laura Herlovich, confirmed Adam’s death to the Las Vegas Review-Journal, stating, “Our family is extremely saddened by the death of Adam. We ask for privacy as we grieve his loss.”

Speaking to Fox News Digital, Rick revealed the exact cause of Adam’s death, attributing it to a fentanyl overdose. “Yes, I can confirm Adam died from a fentanyl overdose,” Rick said. “The fentanyl crisis in this country must be taken more seriously. It seems it is just flowing over the borders and nothing is being done about it. We must do better.”

Fans and Rick’s celebrity friends quickly shared messages of condolence. Donald Trump Jr. wrote, “I’m so sorry man.” Adam’s brother, Corey Harrison, also paid tribute on Instagram, sharing an old baby photo of the two of them in a bath with the caption, “Wax wtf I will always love you bubba.”

Adam was Rick Harrison’s second child from his first marriage to Kim Harrison. Although less involved in the pawn business and the show, Adam did work with his father.

The Centers for Disease Control and Prevention reported a 56.6% increase in overdose deaths, including those involving synthetic opioids, from January 2020 to 2021. The Drug Enforcement Administration lists fentanyl as a Schedule II controlled substance, similar to morphine but about 100 times more potent. Even two milligrams, less than a grain of salt, can be lethal.

Our thoughts and prayers go to the Harrison family.

Rest in peace, Adam.
