Joy-Anna and husband Austin Forsyth released a joint statement Sunday night, about four days after Josh was found guilty at the end of his eight-day trial. Both Joy-Anna, 24, and Austin, 28, appeared in court for parts of the proceeding.
"Over this last year, as you can imagine, there have been a lot of unanswered questions in our minds regarding Josh," their statement, posted to each of their Instagram Stories, read. "We were able to sit through the trial to hear the evidence for ourselves."
"We agree with the judicial system's verdict and we are thankful for the men and women who work tirelessly to protect children and help prevent child sexual abuse material," it continued. "Our hearts break for all CSAM victims."
"We are praying for Anna and her children," the couple concluded, referencing Josh's wife Anna Duggar and their seven kids — Mackynzie Renée, 12, Michael James, 10, Marcus Anthony, 8, Meredith Grace, 6, Mason Garrett, 4, Maryella Hope, 2, and Madyson Lily, 1 month.

The 19 Kids and Counting alum, who previously admitted to multiple incidents of molesting minors when he was a teenager, could get up to 20 years of imprisonment and up to $250,000 in fines. His sentencing is expected in four months, but a date hasn't been scheduled, pending a pre-sentence investigation.
Several of his other family members have spoken out since the guilty verdict was served on Thursday, including sisters Jill, Jessa and Jinger and their respective husbands, as well as cousin Amy Duggar King.

"This entire ordeal has been very grievous. Today, God's grace, through the love and prayers of so many, have sustained us. Our hearts and prayers are with anyone who has ever been harmed through CSAM [Child Sexual Abuse Material]," they wrote.
"In the days ahead, we will do all we can to surround our daughter-in-law Anna and their children with love and support," Jim Bob, 56, and Michelle, 55, continued. "As parents, we will never stop praying for Joshua, and loving him, as we do all of our children. In each of life's circumstances, we place our trust in God. He is our source of strength and refuge. Thank you for your prayers."
Just one day later, news broke that another one of their children — daughter Jana Duggar — has had her own recent legal troubles.
According to a Washington County court document obtained by PEOPLE on Friday, Jana, 31, received a citation for endangering the welfare of a minor on Sept. 9, and has since pleaded not guilty to the charge. The document did not disclose the circumstances surrounding the charge.
