TUCSON, AZ (Tucson News Now) - An hours-long standoff on the southwest side of Tucson ended Friday afternoon and authorities said it appears to have been a murder-suicide.
Deputies believe the suspect was 45-year-old Marie Weber.
She was living at a home on South Old Windmill Lane, near South San Joaquin and West Bopp roads. Investigators believe she shot her father, 71-year-old David Vystrcil, in the morning and took her own life in the afternoon.
Just after 9 a.m. deputies said Weber called her brother to tell him Vystrcil was dead. The brother rushed over to the house and found his father's body and his sister in a back bedroom, reportedly armed with a handgun.
The brother told authorities Weber started firing shots at him. He ran out of the house and called 911.
The Pima County Sheriff's Department's SWAT team surrounded the home. The Hostage Negotiation Team tried communicating with Weber, but were unsuccessful.
Just after 2 p.m. authorities sent a robot inside the home. Deputies said the robot located the body of a woman in the back bedroom with a head injury. Deputies believe the woman shot herself.
Pima County Sheriff Chris Nanos said Weber had been causing problems in the family.
"The whole family describes the sister, Marie, as someone who suffers seriously from mental illness and suffers severely from drug addiction," Nanos said.
Deputies temporarily evacuated houses on South Old Windmill Lane during the standoff. Residents of the street have since been allowed back into their homes.
