A Connecticut man has been arrested after confessing to killing his wife and sending photos of her body to her “new boyfriend,” Law And Crime reports.

On April 16th, at around 3:20 P.M., Pedro Grajalez entered Hartford Police Department’s headquarters and told a front desk officer that he had stabbed his wife to death. According to police documents, the 52-year-old then took out his phone, showed him photos he had taken of a stabbed woman, and stated that her body was in a vehicle just outside of the building.

After detaining Grajalez, the officer located the vehicle and discovered 57-year-old Nilda Rivera alive, but unresponsive. She was immediately rushed to a nearby hospital where she later succumbed to her wounds. Medical professionals who attempted to save Rivera say she “sustained upwards of twenty-five puncture wounds to her chest, head, face, and arms.”

When investigators asked Grajalez what led him to kill his wife, the suspect explained that he had recently discovered that Rivera was having an affair with another man. He claims that after stabbing her, he sent a photo of the aftermath to her “new boyfriend” as revenge.

Grajalez has since been charged with one count of murder, and is being held on a $3 million bond. He is scheduled to reappear in court on May 15th.
