ST. CHARLES, MO (CNN) — A 22-year-old man in Missouri is accused of knowingly trying to spread HIV.
Prosecutors say the former Lindenwood university student engaged in sexual activity with more than 30 people after he discovered he had HIV.
"On that laptop were 32 videos that depicted different individuals engaged in sexual acts with Mr. Johnson." said Tim Lohmar, the St. Charles County Prosecutor.
Michael Johnson was seen with 31 unidentified people in videos taken over 4 months.
Most of them shot on the campus of Lindenwood University in St. Charles.
"It's safe to say that numerous of those videos were taken inside his dorm room, we know that because we recognize the furniture," said Lohmar.
Prosecutor Tim Lohmar says most of victims....not only likely had no idea they were being video-taped, they were clueless that Johnson had HIV and he knew it.
That’s why Lohmar wants any potential victims to come forward immediately, "It's a matter not only of their individual safety but public safety as well."
Lindenwood university school officials tell me they will assist law enforcement with identifying victims.
They say they had no idea the videos existed until just a few days ago.
"I think it's really scary, thinking someone like that is on campus, not thinking about others," said Lindenwood Student Jenny Counts.
Students are shaken up by this latest news, but are glad that Johnson is still behind bars for now...
If convicted of knowingly transmitting HI, he could get up to life in prison.
