A woman apparently shot and killed her 71-year-old father and then turned the gun on herself Friday morning in their home on the southwest side, Pima County Sheriff Chris Nanos said.
The woman suffered from "serious mental illness and was a chronic substance abuser" who was well known to the sheriff department's mental health support team, said Nanos in an interview Friday afternoon.
The woman was identified as Marie Weber, 45, and her father was identified as David Vystrcil.Β
Weber "had been in and out of mental health care facilities for quite some time," Nanos said.
Shortly after 9 a.m., deputies responded to the 4200 block of South Old Windmill Lane after the brother of Weber called to report the shooting, said Nanos.
The brother, in his 40s, was at the scene with his 22-year-old son, Nanos said. He told deputies that his sister called him and said that their father was dead.
Nanos said the man told deputies that he went to the house and found his dad dead in the living room. He then went searching for his sister and found her in a bedroom, said the sheriff.
When he found his sister, she fired two rounds and he left the house and he and his son returned to their home and called authorities, Nanos said. The two then returned and met deputies, he said.
The neighborhood is west of South San Joaquin Road and south of West Bopp Road.
The Special Weapons and Tactics team went to the home but were unsuccessful in making contact with the woman. A robot was sent into the house and the woman was found dead, Nanos said. Her father also was found dead.
Homicide detectives have taken over the investigation.
