MADISON, Wis. — The Wisconsin man whose criminal case was featured in Netlfix's "Making a Murderer" documentary has contracted COVID-19 in prison, his attorney said Wednesday.

Kathleen Zellner tweeted that Steven Avery has the disease but is expected to fully recover. She said in an email to The Associated Press that Avery, 57, is suffering only mild symptoms and is expected to recover.

Avery is serving a life sentence for the 2005 killing of photographer Teresa Halbach. State Department of Corrections spokeswoman Anna Neal said she couldn't share any health information on any individuals in the department's care.

Offender records show Avery is incarcerated at Waupun Correctional Institution. The DOC announced Friday that 184 inmates there have tested positive for COVID-19.

State health officials said that as of Wednesday the state has seen 19,400 cases of COVID-19, an increase of nearly 500 cases since Tuesday, with 616 deaths. The percentage of positive tests stood at 2.9%, however, the second lowest percentage of positives over the last two weeks. According to the state Department of Health Services, 12,624 people, or 65% of total cases, have recovered.
