CORNELIUS, N.C. - Tuesday marked one year since Madalina Cojocari, a North Carolina 11-year-old girl, was last seen.
To date, authorities are still trying to find her as her parents have been a focus in the investigation.
The FBI said Madalina disappeared from her home on November 23, 2022, in Cornelius, North Carolina. She was last seen wearing jeans, pink, purple and white Adidas shoes, and a white t-shirt and jacket. She was reported missing to Bailey Middle School on December 15, 2022.
Madalina Cojocari: What we know about her parents
Shortly after her disappearance, Cornelius police arrested her stepfather, 60-year-old Christopher Palmiter, and her mother, Diana Cojocari, for failing to report the disappearance of a child.

School employees said they contacted Diana several times about her daughter's whereabouts, but it wasn't until December 15, 2022, that the mother walked into the school and told a school resource officer her daughter was missing.

"This is a serious case of a child whose parents clearly are not telling us everything they know," Capt. Jennifer Thompson of the Cornelius Police Department said in a video statement released on social media.
In November 2022, Palmiter drove to his relatives' home in Michigan "to recover some items" after an argument with his wife.

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 November 26, 2022, when her husband returned home to Cornelius, to ask whether he knew where Madalina was. Palmiter apparently asked her the same question in return, according to an affidavit.

When detectives asked Cojocari why she waited until December 15, 2022, to report her daughter missing, the mother said "she was worried it might start a 'conflict' between her" and Palmiter.

The search for Madalina Cojocari
Police have searched throughout North Carolina for Madalina and even expanded their search area away from her hometown.

"We are conducting additional land and water searches as a precautionary measure."
