The former teacher is not alleged to have harmed any student but what did the students learn about the profession when they found out about his past? Would it have made a difference if he had been required to take a pre-employment lie detector test with the question, "Have you done anything that would, if known, disqualify you from obtaining or holding a certification to be a teacher in this, or any other state?"

Mar 27, 2007 - A former teacher won't be teaching again. He left prison after serving a year for throwing the body of his infant son into a quarry.

Thomas Truelson Jr., 27, admitted in 2005 that he threw the baby into a quarry in 1999 after his girlfriend - the baby's mother - killed the newborn. The mother, Jennifer Coleman, 24, is serving six years in prison after pleading guilty to involuntary manslaughter and six other charges.

In 2005, Coleman told friends she had killed the newborn. By then, Coleman was dating someone else, and Truelson had gone on to college and graduated and was working as a teacher at a school for students with behavioral problems at Lorain County Academy in Oberlin.

At the time the baby was killed, he was 19, and she was not yet 16.

TT - Coleman appeared on Oprah Winfrey show last year to discuss her case and urge mothers of unwanted children to turn their babies over to authorities. The baby Coleman killed was born in a toilet in her home. Coleman stabbed the baby to death and Truelson stuffed the body into a rock-filled duffle bag and threw it into a quarry. A recreational diver found it weeks later.
