Police received a call on Tuesday saying a man walked into the offices of Children’s Medical Group (CMG) with a gun and was holding hostages inside the building, the CNN reported, citing Austin Police Department press release.

Several hostages were being held initially, police said, but some escaped and others were allowed to leave, except a pediatrician named Katherine Dodson.

The hostages who escaped the office told cops on the scene that the man was armed with a pistol and what appeared to be a shotgun, police said. He also had two duffel bags. Dr Narumanchi had visited the CMG office a week prior to the shooting and applied for a volunteer position.

The suspect had terminal cancer and had only been given weeks to live, Austin police Lt. Jeff Greenwalt told reporters on Wednesday. “So we feel like his terminal cancer probably played a large part in whatever it was that occurred in his life and what was happening yesterday,” he was quoted as saying by US media reports.

But for now, Greenwalt said, investigators are trying to figure out what could have led to the hostage situation. He called for any of the doctor’s family and friends who might have knowledge about Narumanchi to contact the homicide department.

Earlier, police said hostage negotiators tried to make contact with Narumanchi, but were unsuccessful.

After repeated attempts, SWAT (special weapons and tactic) officers entered the building where they found Dodson and Narumanchi dead from apparent gunshot wounds.

“It appeared that Dr Narumanchi shot himself after shooting Dr Dodson,” according to the police department’s news release. The incident is still under investigation.

“There were five people inside the building when the suspect arrived,” Greenwalt said, adding that they were all employees and no children or patients were present when the incident happened. It wasn’t until the SWAT team was able to send a robot fitted with a camera inside the doctor’s office that police got a full sense of the situation.

“We were able to see that both subjects were dead,” Greenwalt said, referring to Dodson and Narumanchi. The Travis County Medical Examiner will be conducting an autopsy to determine the official cause and manner of death.
