A man suspected of killing his ex-girlfriend in Shenandoah in April was extradited from New York City Thursday afternoon and arraigned before District Judge Anthony Kilker of Shenandoah.

Luis Ramos Nunez-Calderon, 41, was arraigned on charges of criminal homicide, first-degree murder, third-degree murder, voluntary manslaughter, criminal trespass and two counts of aggravated assault.State police at the Frackville barracks, who took over the investigation of the death at the request of Shenandoah police, said Nunez-Calderon is charged with killing Wendy Contreras-Hernandez, 38, sometime between 12:25 p.m. and 4:08 p.m. on April 29.In an affidavit of probable cause filed by Tpr. Melissa Kyper of the Frackville barracks of the PSP, Shenandoah police were dispatched to the victim's home, 518 W. Centre St., at 12:35 p.m. that day for a domestic dispute in progress. Officers were unable to make contact with either party.Later in the day, school authorities called Lydia Contreras, Wendy's mother, when the woman failed to pick up her daughter at school.After picking up her granddaughter, they went to the home and found Contrares-Hernandez lying on the bathroom floor in a pool of blood. The woman had been stabbed in the neck. Police determined a knife was missing from a butcher block in the kitchen.A canvas of the neighborhood was conducted, giving officers a chilling view of the relationship between the victim and her ex.Neighbors told of multiple domestic assaults, even the one earlier in the day, when they saw Nunez-Calderon physically abusing Contrares-Hernandez, dragging her in to the home by her hair. One neighbor told officers he had provided shelter to the victim for several days earlier, due to her fear of her ex-boyfriend.Witnesses also told police they saw Nunez-Calderon later in the day at a restaurant and bar in the borough. They noted he had obvious blood on his clothing. A truck driver said he drove the suspect to 180th Street and Broadway in North Manhattan, New York City, and there was blood on his clothes. The trucker told police he noticed Nunez-Calderon was weeping and saying he needed to talk to his mother.State Police determined Nunez-Calderon was traveling a path leading to a relative's home in New York City. U.S. Marshals and New York City Police were able to arrest him without incident the next day.Kilker explained to the defendant, through an interpreter, that the maximum penalty for first degree murder and criminal homicide is death or life in prison, sending him to the Schuylkill County Prison, Pottsville, after the arraignment.Nunez-Calderon is scheduled for a preliminary hearing at noon Sept. 11 in Kilker's office.
