Police on Wednesday identified the three people who drowned in an apartment-complex swimming pool as a 15-year-old girl, a 16-year-old boy and a 21-year-old man. None of them lived in the complex, police said.
All three drowned, spokeswoman Kammie Michael said, and there were no indications of foul play.
The three are Abril Yuliana Flores-Ojeda, 15; Brian Manuel Benites, 16, and Luis Enrique Delgado-Romero, 21.
They lived in Durham, but not at the Chapel Tower Apartments, where the pool is, Michael said.
The three were found submerged in the pool at the complex shortly after 3 a.m. Tuesday.
Rescue workers tried to revive them, but they were pronounced dead at Duke University Hospital.
Investigators said there were no signs that the victims had been electrocuted, Michael reported.
The swimming pool at the complex on Morreene Road in west Durham passed an inspection earlier this month, county records show.
"When it was inspected 10 days ago, everything was OK," Khali Gallman, a spokeswoman for the department, said Tuesday. "We are awaiting an investigation by the Police Department to be completed. There has been lots of speculation, but no one knows for sure."
The county inspection report indicated that the pool's water was clear enough to see the bottom, and that pool workers kept a daily record of the water quality and kept a test kit on site.
The inspector also found that the pool's main drain cover was secure and working properly. It was also noted that the pool's surface was free of floating debris and that depth markings for the 8-foot water were visible and clearly located.
The only issue found during the 30-minute inspection was that a ladder was missing a "bumper" and needed to be flush with the pool's wall.
Three investigators, two wearing blue gloves, marked items as evidence, including a beer can.
A maintenance worker said the pool is closed on Mondays and that the gate was locked the last time they saw it around 9 a.m. Monday.
A resident said that about 3 a.m. Tuesday, someone was knocking on doors. He called 911, peeked out his door and saw a man and a police officer pulling a body out of the water.
The resident, who did not want his name used, said he jumped over the fence and pulled a second person from the water and performed CPR.
The Chapel Tower swimming pool inspection on June 8 do not include checking for potential electrical improprieties, said John Williams, Durham County's swimming pool inspector, said in an email Wednesday to The News & Observer.
Williams said the agency last year sent recommendations to public pool managers throughout county to have their pool electrical systems and components checked by a qualified, licensed electrician.
The countywide electrical inspections were in response to the 2016 death of Rachel Rossof, a 17-year-old lifeguard and Enloe High School student who was electrically shocked and then drowned in a pool in northern Wake County.
