Updated on March 25 at 7:30 p.m. with new figures and a statement from the sheriffโ€™s office.

As the coronavirus begins to spread inside the walls of the Cook County jail, officials have released at least 300 people so far this week, according to the Cook County Sheriffโ€™s Office.

But about 180 people were booked into the jail on Monday and Tuesday, according to an Injustice Watch analysis of the sheriffโ€™s data.

As of Wednesday evening, at least 17 detainees and five employees had tested positive for the virus that causes COVID-19, according to the sheriffโ€™s office, with test results pending for 31 other inmates.

On Monday, Cook County Judge LeRoy Martin, who oversees the courtโ€™s criminal division, ordered expedited hearings on releasing inmates with underlying health issues, those facing misdemeanor and non-violent felony charges, and those with money bonds they canโ€™t afford.

Cook County Public Defender Amy Campanelli had argued in court Monday for a broader release of hundreds of detainees who fit those categories and whose release prosecutors had agreed to. But the Stateโ€™s Attorney opposed her motion, and Judge Martin ruled that the courts must make decisions on a case-by-case basis.

The Cook County Jail population has dropped by 300 people, or about five percent, since the beginning of March.

In an emailed statement, Cook County Stateโ€™s Attorney Kim Foxxโ€™s office said it โ€œhas stood ready to reduce the jail population responsibly in the interest of both public health and safety.โ€ However, the statement also blasted Campanelli for allegedly petitioning for the release of some people who have been charged with violent crimes, including murder and domestic violence.

Campanelliโ€™s office could not immediately be reached for comment.

The jailโ€™s overall population has decreased by five percent since the beginning of March, when the first positive case of the coronavirus hit Illinois, with most of that change coming in the past week. As of Wednesday morning, about 5,300 people were locked in the jail, according to sheriffโ€™s data.

โ€œA lower population at the jail is something that is good for our staff and for the detainees who are released,โ€ said Matt Walberg, a spokesman for the Cook County Sheriffโ€™s Office. โ€œThis helps protect our staff and detainees by creating more space for distancing in the jail. This flexibility allows us to continue additional measures to aggressively combat the spread. Weโ€™ve been supportive of our partners efforts to release non-violent offenders and we will continue to provide them the information they request.โ€

Activists had asked Cook County Chief Judge Timothy Evans to โ€œimmediately depopulate the jail and the Juvenile Temporary Detention Center as much as possible,โ€ in an open letter released last Thursday.

On Wednesday, advocates said the courts still werenโ€™t moving quickly enough.

โ€œWeโ€™re moving slowly in the right direction, but certainly not at the speed that weโ€™ve seen in other jurisdictions and not at the speed necessary for folks to get the health outcomes they deserve,โ€ said Sharone Mitchell, a former public defender and director of the Illinois Justice Project, one of the advocacy groups that signed the letter. โ€œThe idea that an individual case-by-case determination would be the most efficient way of doing this is incorrect.โ€

In other states, judges have released people from jails en masse. In New Jersey, for example, the stateโ€™s chief justice ordered all those jailed on probation violations or municipal court violations released from county jails, expected to be close to 1,000 people, according to The New York Times. In Los Angeles, Sheriff Alex Villanueva released about 1,700 of the countyโ€™s 15,000 jail inmates, according to CBS News.
