UPDATE: Dallas man arrested for killing wife and two sons because he was annoyed with them

The Dallas Police Department is investigating a homicide that occurred earlier this morning at the Rosemont Apartments, 2605 John West Road.
At around 11AM, a man called 9-1-1 and told dispatchers that he had killed his family. Police immediately responded to the scene and located the bodies of a woman and two teenagers. All had been shot and killed.
An arrest warrant indicates the suspect, a 56-year-old man, got into an argument with his wife and children around 10AM. The man told detectives that he had a headache and they were being too loud. They were allegedly yelling at him and “telling him nothing was wrong.”
During the argument, the man grabbed a gun and shot all three of them.
The wife, who was in her 50’s, and her two teenaged sons, 13 and 16, were all pronounced deceased at the apartment.
The suspect was arrested and has been charged with Capital Murder.
