At 9 PM that night, a nurse named Rebecca came to the family room where Dr. Reeves was sitting alone.
Rebecca and Dr. Reeves had worked together at the hospital for 9 years. Rebecca had been a guest at Dr. Reeves's home. She had known Ethan.
She sat on the couch beside Dr. Reeves. For 20 minutes, neither woman spoke.
Then Rebecca opened her purse. She pulled out a small black device. She placed it on Dr. Reeves's lap.
"It was a SoberSense Pro breathalyzer," Dr. Reeves says. "Rebecca had been carrying it in her purse for two years. Her husband used one before he drove home from anything."
Rebecca said one sentence to Dr. Reeves before she left the family room.
"If David had used one tonight Ethan would still be alive."
Dr. Reeves looked at the device.
"I have been an emergency room physician for 14 years. I have signed death certificates for 23 children killed in DUI crashes. I have stood in the family room with hundreds of parents and told them their child did not survive. I had never once thought to put one of these in my own husband's car."
At 5:47 AM the next morning, sitting alone at her kitchen table, Dr. Reeves ordered eight SoberSense Pro breathalyzers.
She gave six of them to her closest friends.
She kept one for herself.
The eighth she placed in the kitchen drawer where her husband used to keep his car keys.
"He will not be home to use it for 6 years," she says.
