“Two weeks ago, tragedy struck our family and it has left us completely shattered,” Elizabeth wrote on Instagram. “My sweet, loving, and caring dad went to heaven. We’re trying to figure out how to navigate our lives and move forward without him.”

“Please respect our privacy during this difficult time,” she added. 

Chuck was a familiar face to 90 Day fans, appearing frequently in segments with his daughter and her husband, Andrei Castravet

Elizabeth, 34, first appeared on 90 Day Fiancé Season 5 in 2017, alongside her Moldovan husband-to-be. The show followed the couple’s journey to the altar, including her family’s concerns about their relationship. Her dad in particular saw some major red flags in his daughter’s choice of a husband, and he didn’t hesitate to share his opinion on their relationship and their finances. He also supported the couple financially as Andrei struggled to establish a career in the U.S. following his marriage. 

Despite some hurdles, Elizabeth and Andrei said “I do” and went on to welcome two children. They continued to participate in the 90 Day franchise, appearing in 90 Day Fiancé: Happily Ever After? Seasons 4-7. After taking a break, they returned for Happily Ever After? Season 9, which premiered earlier this year.

Elizabeth and Becky’s sister Jenn “Jaylyn Davis” Potthast also posted about her dad’s death on her Instagram Story.

“There are no words that I can form currently to express all who was my dad and all of my emotions I’ve been feeling … I’ve been blessed in my life that this is the first time I’m dealing with grief of this magnitude and someone like this close to me passing. I still doesn’t feel real, and the numbness hasn’t subsided … I love you dad.”
