911 calls and names of victims released in Casa Grande fire

CASA GRANDE, AZ - The Pinal County Sheriff's Office released the names of the three suspected victims late Saturday morning, however said the Medical Examiner's Office still needs to confirm the identities using dental records.        

Authorities say those three victims are most likely Dr. Joyce Bonenberger Brough, her husband Dennis Brough and their 11-year-old son Trevor.

Neighbors reported a large house fire around 6:37 a.m. Friday morning at the Desert Highlands subdivision and called 911. Crews arrived to find the home completely engulfed in flames. Desert Highlands is located northeast of Casa Grande.

Casa Grande Regional Medical Center officials also say they believe Bonenberger is among the dead and for the first time we are hearing the 911 calls neighbors made as they watched her home get consumed by fire.

"My neighbor's house is on fire," one neighbor is overheard telling the 911 dispatcher Friday morning.

At one point of another 911 call the crackling of the fire can be heard in the background and the caller tells the dispatcher that "the tile on the roof is starting to come off."

That same caller described a fellow neighbor's attempts to save anyone who may have been inside.

"Somebody's kicking the door…I think he broke a window and he's yelling to see if somebody might be there."

Kathy Walsh is a coworker and neighbor of Bonenberger who says she was an asset to the hospital and will be missed.

"We're very saddened by it...Very saddened. I was praying all day that maybe she was gone or out of town or something when we got the news," said Walsh.

Even though the Brough family is the presumed victims, the medical examiner will still need to make the positive identification as well as determine the cause of death.

The president and CEO of the Casa Grande Regional Medical Center released the following statement Saturday:

Dr. Bonenberger was a beloved member of the CGRMC Medical Staff. She was a surgeon who made a real difference in the lives of many patients and staff members in our community. She will be remembered for her sense of humor, willingness to train medical students, and her interest in improving the lives of her patients through surgical interventions. Her contributions to CGRMC are invaluable.

Bonenberger joined the CGRMC staff in 1999.

Authorities said the body of an adult male was found in the garage, an adult female was found in the master bedroom and the body of a child was in another bedroom, according to a release.

Detectives and arson investigators continue to investigate the cause of the fire.
