It's only been four months since Jim Bob Duggar's mother, Mary Duggar, died in a freak drowning accident.
And now, the family is forced to cope with the loss of another life taken before its time.
Multiple sources have now confirmed that Rebecca Waller was killed in a traffic accident near her home in Harris, Minnesota on Wednesday.
She was 22 years old.
Rebecca is the sister-in-law of Anna's sister Priscilla Waller.
Priscilla's husband, David Waller, shared the news of his sister's passing on social media:
“With heavy hearts, we received a phone call today that David’s youngest sister, Rebecca went home to heaven today, October 2, at around 8:30 a.m.," he wrote.
"The twenty-two years of life that God gave us with her seem so short, but in light of eternity all of our lives are short.”
“The most important thing is a relationship with Jesus Christ that Rebecca evidenced by the fruit of her life.
"She is in heaven today, not because she was a good person, but because she trusted in the Lord Jesus Christ as her personal savior," he added.
"The instant her car was struck, she passed from earth to heaven and is in the presence of the Lord.”
According to police reports obtained by Radar Online, Rebecca was killed instantly when she was struck by two cars after running a red light and attempting to “cross westbound traffic."
While Anna lived far away from her Minnesota relatives, insiders say she has always maintained close relationships with her siblings and their spouses.
Currently, Anna is expecting her sixth child, and this is the second loss she has suffered during the pregnancy.
Anna has paid tribute to Mary Duggar numerous times on social media, and those who know the family best say she was especially close to the woman whom she thought of not as an in-law, but as her own grandmother.
Anna has not yet spoken publicly about the loss of her brother-in-law's wife, but knowing how important familial bonds are within the Duggar clan, it's safe to assume she's overcome with grief.
Our thoughts go out to the Duggar and Waller families during this difficult time.
