DURHAM, N.C. _ A swimming pool at an apartment complex in west Durham where three people were found dead early Tuesday passed an inspection earlier this month, county records show.
Police found two males and one female submerged at the Chapel Tower apartments after being called shortly after 3 a.m.
The three, whose ages and identities were not immediately released, were pronounced dead at Duke University Hospital, Durham police spokesman Wil Glenn said.
By Tuesday evening, police had not disclosed a cause of death.
The pool was last inspected June 8, when it met county standards, according to documents from the Durham County Health Department.
"When it was inspected 10 days ago, everything was OK," said Khali Gallman, a spokeswoman for the department. "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.
The inspector found no discrepancies with the pool's automatic chlorine and bromine feeders that disperse the disinfectants, nor anything improper with the pump and filter.
On Tuesday morning, police at the Chapel Tower pool collected items, possibly clothing, they found behind a green chain-link fence and placed them in brown bags.
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 the gate was locked the last time they saw it around 9 a.m. Monday.
A resident said around 3 a.m. 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 resident said all three people appeared to be teenagers.
The Chapel Tower swimming pool is closed on Mondays and opens at 11 a.m. other days.
Gallman, the health department spokeswoman, said an inspector will visit the site again Wednesday morning.
"The pool will reopen when police complete their investigation," she said.
