Los Angeles County’s jails are emptying fast as sheriff’s department officials try to limit the possibility of a disastrous outbreak of coronavirus behind bars.

For almost two weeks, Sheriff Alex Villanueva said he was looking for as many inmates as possible to safely release. On Tuesday, he said the number so far was 1,700 inmates, or about 10% of the county’s entire jail population.

All of those inmates had fewer than 30 days left on their sentences. And all were convicted of nonviolent misdemeanors, he told the Los Angeles Daily News.
