WOOLWICH, Maine — A Woolwich man convicted of sexually assaulting a horse at the University of Maine a decade ago was arrested Monday because police say his computer contained images of child pornography.

William Diemer, 31, formerly of Brunswick, was arrested Monday at his workplace in New Harbor, according to a news release from Stephen McCausland, spokesman for the Maine Department of Public Safety. Diemer was charged with 15 counts of possession of sexually explicit material.





After being arrested and taken to Two Bridges Regional Jail in Wiscasset, Diemer was released Monday on $5,000 unsecured bail.

Maine State Police seized Diemer’s computer last fall after receiving a tip, McCausland said in the release. After his computer was analyzed by the state’s computer crimes task force, the Sagadahoc County district attorney’s office authorized Diemer’s arrest, McCausland said.

None of the children allegedly depicted in the pornography are believed to be from Maine.

In 2004, Diemer pleaded guilty to cruelty to animals after he was caught sexually assaulting a mare at the University of Maine Witter Farm in Orono.

He was sentenced to nine months in jail with all but 30 days suspended, required to undergo counseling and prohibited from owning or possessing domestic animals for the rest of his life.

Diemer is married but does not have any children, according to McCausland.

He is scheduled to appear in Sagadahoc County Superior Court on March 11.

No further information was immediately available on Tuesday.
