SAGINAW, MI -- A Saginaw man facing a rape charge told medical officials he is HIV-positive, leading to an additional charge against him, prosecutors say.

Lonnie A. Perkins

Lonnie A. Perkins, 48, faces four felonies in connection with a Thursday, Jan. 28, incident on the city's West Side.

Perkins is charged with two counts of first-degree criminal sexual conduct and single counts of unlawful imprisonment and sexual penetration with an uninformed partner.

His arrest warrant alleges that he used force or coercion to rape a 51-year-old woman and did so knowing he was diagnosed with the virus without telling the woman of his condition.

Saginaw County Chief Assistant Prosecutor Christopher Boyd alleges the incident occurred after the woman came over to Perkins' home.

Perkins' arrest warrant also alleges he injured the woman during the course of the rape. Boyd said the woman had injuries to her face and bruises on her body.

First-degree criminal sexual conduct, the most serious of sexual offenses, involves penetration and carries a maximum penalty of life in prison with the possibility of parole. The imprisonment charge carries a 15-year maximum penalty, and the HIV-related charge carries a four-year maximum penalty.

Boyd acknowledged his office's filing of the uninformed partner charge is rare. His office filed the charge after medical workers said Perkins told them he was HIV-positive, Boyd said.

Saginaw police on Friday arrested Perkins, and he faced Saginaw County District Judge M.T. Thompson for arraignment on Monday morning.

Thompson entered a not guilty plea on Perkins' behalf and ordered him held on a $100,000 bond.

Perkins remains jailed and is scheduled for a Feb. 18 preliminary hearing before Thompson.
