A man accused of burying his 11-month-old son alive in a rural grave was convicted early Wednesday of first-degree intentional homicide.

Peter Chapman, 40, wept several times during testimony that began last week but showed little emotion when the jury's decision was read after about six hours of deliberation.Chapman originally said the child had been kidnapped, according to police, then led them to the shallow grave, insisting he had panicked and buried his son, Michael, after the child died at his home.

Sentencing is scheduled on March 22. The offense carries a mandatory penalty of life in prison.
