For the second time this year, a professor at the University of Iowa has taken his own life after being accused of sexual harassment. .

On Wednesday, just a week after he was accused of sexual harassment in a lawsuit, Mark Weiger killed himself.

He was found in his car, dead from carbon monoxide poisoning, with the garage door at his home closed. Authorities said he left a note.

In August, [66-year-old political science professor] Arthur H. Miller was arrested on bribery charges and accused of telling female students that he would give them higher grades if they let him fondle their breasts. In one case, he is alleged to have grabbed and sucked on a student's breast and then sent her an e-mail telling her that she had earned an A+. He then shot himself in a local park.
