The sister of missing Minnesota mom Madeline Kingsbury says the arrest of her ex, the father of their two children, was a “silver lining” for the grief-stricken family.

In a TikTok posted Wednesday night, Megan Kingsbury seemed relieved by the arrest of Adam Fravel, who’s facing murder charges after cops found human remains in the brush near a highway 45 miles south of where Madeline Kingsbury was last seen alive.

“Finally, he’s been arrested,” Megan Kingsbury says in the video, noting she’s still waiting for more details from authorities.

Fravel’s arrest comes weeks after he insisted he had nothing to do with the sudden disappearance of the young mom.

“The whirlwind is just starting all over again. This is definitely a silver lining,” Megan Kingsbury adds. “We’re glad that he’s in custody and that he’s not walking around as a free man anymore.”

The remains were located Wednesday using information collected during a police probe, according to the Winona Police Department. The Southern Minnesota Regional Medical Examiner’s Office is working to confirm the identity..

Kingsbury, 26, vanished March 31 after dropping off her two kids, ages 5 and 2, at daycare in Winona with Fravel.

Police described her sudden disappearance as “involuntary and suspicious.”

Fravel, 29, told police he left their house at 10 a.m. and Kingsbury wasn’t there when he returned, but her phone, wallet and jacket were. He was the last person to see her alive, according to authorities.

“I want the mother of my 5-year-old and 2-year-old to be found and brought home safely,” Fravel said in his statement. “I want that more than anything.”

More than 2,000 people volunteered in the search for Kingsbury. Authorities also said they have served “numerous search warrants” as part of the effort. 

Kingsbury’s family is in the middle of a bitter custody battle over her children with Fravel, who petitioned for custody after their mother vanished.

The two kids are living with Kingsbury’s parents, although they are technically in the custody of Winona County.

At the time Kingsbury disappeared, she and Fravel were no longer in a relationship. But while they were broken up, the pair were still living together as Kingsbury looked for a new place to live without him.

The Winona Police Department said it would have a news conference Thursday afternoon in the Winona City Council Chambers.

The city of about 25,000 people is roughly 120 miles southeast of Minneapolis.
