A 15-year-old upstate New York girl was raped, suffocated and buried days later in an apple orchard by her brother-in-law, police said.

The remains of Katherine Sanchez were found Friday, more than a month after she was reported missing.

Carlos Cardenas, 21, is being held on second-degree murder charges in Orleans County.

Police say Cardenas raped the teen while she was babysitting at his house and killed her when she threatened to tell her sister, WKBW-TV reported.

Cardenas kept Sanchez’s dead body in his basement for a couple of days before taking it to the orchard, said police.

"He deserves the death sentence, that's what he deserves," Kimberly Cardenas said of her husband, whom she said acted normally while Sanchez was missing. "He's demented. He's a sick man."

Police said Carlos Cardenas, a native of Mexico, is illegally in the U.S.

"She was an angel," Kimberly Cardenas said of her sister, "an angel on earth."
