MODESTO, Calif. -- A Modesto man has been sentenced to six months in jail for having sex with two women and not telling them he was HIV positive.

William Wilcox (pictured, left), 35, said he was sorry Thursday for what he did, but his victims said that's not enough.

One of the victims, who wanted to be called "Mary" to protect her identity, said it will be an agonizing six months before she finds out if she has a potentially deadly virus.

"I found his medication, and the paper said that he had HIV. And I panicked," Mary said.

Mary went to the Stanislaus County District Attorney's Office and found out there was another victim.

"During this time period, there was another individual that he was engaging with at least one sex act," said Stanislaus County Deputy District Attorney Nate Baker.

Wilcox was arrested, pleaded guilty and sentenced to six months in county jail.

One of the victims said she will fight to get stricter legislation.

By law, Wilcox can only be charged with a health and safety code violation. It can only turn into a felony if prosecutors can prove there was malicious intent.

Wilcox said he was in denial about having HIV and never intended to give it to his partner.

"I would gladly give up the rest of my life to ensure that she would never test positive," Wilcox said.

Wilcox said he plans to remain abstinent when he is released from jail.
