A 23-year-old man accused of exposing other gay men to HIV while attending college in suburban St. Louis tested positive for the virus that causes AIDS two years earlier in Indiana.

Prosecutors disclosed the new evidence Tuesday during their opening statement in Michael L. Johnson's trial in St. Charles County. The former wrestler at Lindenwood University in St. Charles is accused of infecting two of his sex partners and endangering four others.

His public defender declined to make an opening statement and did not address Johnson's earlier test while cross-examining three prosecution witnesses.

The former state high school wrestling champion from Indianapolis could face decades in prison if convicted. Johnson also was a junior college national champion at Lincoln College in Illinois.
