Chandler couple Vu Tran and Siobhan Grogan told police they often kept their 8-year-old son -- who has mental and physical disabilities -- locked in a bathroom. Police questioned them a year ago because they left the boy there, and the maintenance manager from their apartment complex found the boy locked in the bathroom, naked and standing in two inches of water, while the toilet was overflowing, while he was investigating a leak. They pleaded guilty to attempted child abuse. They were sentenced to five years of probation.
