After making the grisly finding during a routine traffic stop, an American motorist was arrested with the remains of her young nephew and niece in the trunk of her car, authorities said Friday.

Nicole Johnson, a resident of Baltimore on the east coast, faces a slew of accusations, including child abuse in the deaths of a seven-year-old girl and a five-year-old boy.

According to the Baltimore Sun, the 33-year-old placed her niece’s body inside a suitcase and put it in the trunk as early as May of last year, while continuing to drive the car regularly.

She placed the boy’s body next to his decomposed sister a year later, wrapped in a plastic bag, the paper reported.

Police stopped her for speeding on Wednesday and decided to impound the car when it emerged she did not have the correct papers.

According to the paper, one officer told Johnson the vehicle was going to be towed and she replied: “It don’t matter, I won’t be here in five days.”

She added that “y’all going to see me on the news making my big debut,” the paper said, citing a police report.

The two children had been entrusted to Johnson’s care, she said, in 2019 by her sister.

Johnson admitted during questioning that she had hit her niece several times, the Sun said, causing the youngster to hit her head on the floor. She did not explain how the boy died.
