An American boy who was found unconscious in an Arizona swimming pool and pronounced dead was later discovered alive in the hospital’s “cold room,” a newly released police report shows.

The 18-month-old boy’s family frantically called police after he was found face down in the pool of a home in the Phoenix-area suburb of Gilbert on Feb. 8.

First responders were dispatched and life-saving measures were taken, before the boy was transported to hospital and pronounced dead an hour later.

According to the police report, officers told the hospital’s doctor, Dr. Aryan Toosi, that they had seen signs of life. The doctor responded, “please do your thing and let me do mine,” the report says.

“I went to medical school for a reason,” Toosi said.

The family had gathered to watch the NFL Super Bowl game when police were called to the scene for a report of a drowning.

Gilbert police arrived at the home around 5:30 p.m. MST (00:30 GMT), before the boy was taken to Mercy Gilbert Medical Center and pronounced dead at 6:20 p.m.

“If there are no objections, I would like to announce the time of death,” Toosi said, according to the police officer’s body camera video obtained by a local NBC News affiliate.

“Time of death 18:20. Moment of silence,” the doctor said.

A transporter from the Maricopa County Medical Examiner’s Office arrived at the hospital five hours later and found the child still breathing, according to police.

He was airlifted to another hospital where he recovered and has since been released.

The boy’s medical records were not included in the police report, leaving uncertainty about what exactly happened.

The doctor’s attorney, Scott Holden, told the Associated Press “that there is much more to this case, both factually and medically, than has been reported so far.”

The BBC has contacted Toosi’s lawyer for comment.

Police recommend filing neglect charges against the parents.

According to the police report, investigators said there was a strong odor of marijuana in the home, leading them to believe the boy may have had unsupervised access to the pool.

The Maricopa County Prosecutor’s Office has not yet said whether it will seek to file charges.

Mercy Gilbert Medical Center said in a statement that the hospital conducted “a thorough review of all aspects of the care provided to learn what happened and make significant changes to strengthen our care.”

The hospital called it “a heartbreaking situation” and declined to reveal further details.
