Authorities in the US state of Massachusetts are trying to find out how a body lay unnoticed in a swimming pool for more than two days as the public continued to use the facility.
Marie Joseph, 36, had used a slide at the Veterans Memorial Pool in Fall River on Sunday but failed to return to the surface.
The body was found on Tuesday when teenagers broke in for a night swim.
The permit for the pool, described as "cloudy", had expired six months ago.
The woman's body, which was found resting on the bottom of the swimming pool, reportedly went unnoticed when a city health inspector examined the pool earlier on Tuesday, the Boston Globe newspaper reported.
The inspector described the public pool as cloudy in an examination report.
The swimming pool had not previously been inspected in about a year, and its permit had expired on 31 December 2010, Fall River mayor William Flanagan said on Thursday.
Mr Flanagan has ordered the immediate inspection of 21 pools in the city, while Massachusetts has closed dozens of state-run swimming pools as the investigation into Ms Joseph's death continues.
Two inspectors, who had stopped by the pool on Monday, have been placed on administrative leave.
An autopsy on Ms Joseph's body has been completed but the results have not yet been published.
Ms Joseph, a native of Haiti, had five children and worked as a housekeeper at a hotel in the state of Rhode Island.
