An Ohio man accused of not telling his mistress that he was HIV-positive has been charged with murder after the woman's death from AIDS.

Ronald Murdock, 51, of Toledo, also is charged with felonious assault. Lucas County court records listed no attorney for the jailed man ahead of his arraignment Tuesday.

The indictment alleges that Murdock had sexual contact with someone without disclosing that he had the virus that causes AIDS.

WTVG-TV reports that Murdock's girlfriend, 51-year-old Kimberly Klempner, had AIDS and died in February.

Her son, Josh Klempner, says Murdock dated the woman for years without telling her that he had HIV and that he was married.

'It would be different if he would let people know that he had it before he got in that relationship. He didn't so that right there tells me and everybody else that he has no care. The only person he's worried about is himself,' Josh Klempner said.

Klempner's son Josh says that Murdock never told his mother that he had HIV in the five years they had a sexual relationship

'He should of warned her. He should have told her. I don't want him out here on the streets. The way I see it they should just bury him under the jail,' he added.

Josh said his mother only found out that Murdock had HIV when she told him she was HIV positive in 2015 and he didn't seem bothered about it. Then she looked through his medicine cabinet and made a startling find.

'My mother found out about some pills he had. She stayed the night at his house one night and she felt something was up. She did some snooping and ran across a few pill bottles. She did a little research on them and found out that way,' Klempner said.

When Murdock's wife discovered the affair, she also told Klempner about Murdock's HIV status.
