CHARLOTTE, North Carolina – The parents of missing North Carolina girl Madalina Cojocari "had no friends" and were mostly "quiet" during annual friend group vacations, according to an acquaintance of the family who attended the same vacations.

The 11-year-old's parents, Diana Cojocari and Christopher Palmiter, have been arrested and charged with failure to report a missing child to law enforcement after Madalina's disappearance from her hometown in Cornelius, which is just north of Charlotte, around Nov. 23, 2022, that went unreported for weeks. 

"Our friend who we know [the Cojocari family] through said that to us, like, they had no friends. That's why they would come to this family-friend get-together. That was really one of their only social times," Michele Clark Triscitti, one of Diana Cojocari's 16 friends on Facebook, told Fox News Digital. "I'm not close enough to them to have known that, and that just came to light when we spoke to our mutual friend about it."

Clark Triscitti describe Diana Cojocari as "quiet" and "kind of on the outskirts" during the group vacation, which was organized by a big group of friends who were close with Palmiter "years ago."

"Nothing out of the norm. . . . Just more of a quiet, to-themselves kind of family. They did engage and talk and interact and have conversations with everyone — just more quiet," Clark Triscitti explained.

"We're pretty shocked. My son would play with Madalina every year when we would have these vacations. They would hang out and play and do kid things, so yeah, it's pretty shocking," Clark Triscitti said, adding that Madalina was "one hundred percent" a normal little girl, based on what she had observed during the group trips.

Madalina's disappearance wasn't made known to police until Dec. 15, when Cojocari told school officials and local police that she had last seen her daughter go to her bedroom the night of Nov. 23 around 10 p.m. after she and Palmiter got into an argument, court documents state.

On Nov. 24, Palmiter drove to his relatives' home in Michigan "to recover some items." Cojocari went into her daughter's room around 11:30 a.m. that morning to discover that the 11-year-old was gone. She waited three days, until Nov. 26, when her husband returned home to Cornelius, to ask whether he knew where Madalina was.
