(MCT) — Wisconsin’s medical examining board has launched an investigation into a prominent Milwaukee pediatrician who practiced for years after he admitted to the Boy Scouts of America that he had molested two boys in 1987.

Dr. Thomas Kowalski was expelled from the Boy Scouts that year after saying he had masturbated while fondling two teens under his care at a Wisconsin Scout camp where he was serving as a volunteer doctor. The allegations were detailed in one of hundreds of confidential files on suspected sexual abusers reviewed by the Los Angeles Times in recent months.
