A Delaware County man called police Sunday morning to tell officers that he had killed his wife and mother, officials said Monday.

And when police arrived at Iqbal Singh’s home in Newtown Township, they found the 62-year-old covered in blood, suffering from self-inflicted stab wounds. Inside were the bodies of the two women.

Singh was charged Monday with first- and third-degree murder, court records show, and remained in custody, denied bail given the nature of the charges. There was no indication that he had hired an attorney.

At Singh’s home on Rockwood Road, police found his mother, Nasib Kaur, lying unresponsive on the first floor with her throat slit. Singh’s wife, Jaspal Kaur, was found upstairs, similarly wounded. Both women were pronounced dead at the scene, according to the affidavit of probable cause for his arrest.

The motive in the slayings was unclear Monday.

Singh’s son and daughter told police they had tried to call him and their mother on their cell phones early Sunday, but received no answer, the affidavit said. When they called their parents’ house, the affidavit said, Singh told them that he had killed the two women and told them to “call the police to come get me.”
