Minutes after police left what they called a "domestic dispute," a man called from the home to say he killed his wife and daughter.
The daughter died at the scene and the wife was critically wounded, Pennsylvania police say.
East Pennsboro Township police were called to the suspect’s home in the Enola area for a domestic dispute on April 10. Officers said they found the dispute was “civil in nature,” involving John Miller, 78, and his adult daughter, according to the department.
Police left the scene. A short time later, Miller called 911, saying he shot and killed his wife and daughter, according to police.
Officers returned to the scene and arrested Miller without incident.
His daughter was found dead inside the home, police said in a statement. His wife was still alive, but had been shot. Police completed first aid, and emergency personnel took her to Penn State Holy Spirit Hospital with life-threatening injuries.
The names of the victims have not been released.
Miller was taken to Cumberland County Prison and was arraigned on one count of criminal homicide.
The investigation continues and anyone with information is asked to contact police at (717) 732-3633.
