David Lee Mangum of Dexter, Missouri, was sentenced to 30 years for “reckless exposure to HIV infection,” reports KFVS news.

Mangum had pleaded guilty to the charges last month and also told police he had had more than 300 sexual partners since he was diagnosed HIV positive in 2003. Reports do not address whether Mangum has been on HIV treatment or whether he is virally suppressed.

The charges against Mangum arose after his former live-in partner tested positive for the virus. The two had lived together off and on from November 2012 to June 2013. The former partner told police he ended the relationship once he found out Mangum was unfaithful. But at the beginning of the relationship, the partner said, Mangum had told him he was HIV negative.

According to KFVS, when police asked Mangum why he didn’t disclose his HIV status, he said “fear of rejection.”

Health experts in Stoddard County are recommending anyone who may have been exposed to the virus to get tested.

Mangum’s sentencing is the latest in a string of HIV criminalization cases in Missouri to make headlines. Earlier this month, former college wrestler Michael Johnson was sentenced to 30 years for infecting a partner with HIV, and Robert Smith was arrested on charges of attempting to expose another person to the virus by seeking sex on social media. Both cases are in the St. Louis area.
