Gene Weingarten, of the Washington Post, tells the deeply touching story of parents who have accidentally killed their toddlers by leaving them strapped into child seats in parking lots on hot days. Weingarten is a brilliant practitioner of an art that seems to be fading away: long form journalism. He has been a favourite of ours since we came upon his Pearls Before Breakfast (read it if you haven't already).

When a hospital emergency room nurse described how the defendant had behaved after the police first brought him in, she wept. He was virtually catatonic, she remembered, his eyes shut tight, rocking back and forth, locked away in some unfathomable private torment. He would not speak at all for the longest time, not until the nurse sank down beside him and held his hand. It was only then that the patient began to open up, and what he said was that he didn't want any sedation, that he didn't deserve a respite from pain, that he wanted to feel it all, and then to die.

The charge in the courtroom was manslaughter, brought by the Commonwealth of Virginia. No significant facts were in dispute. Miles Harrison, 49, was an amiable person, a diligent businessman and a doting, conscientious father until the day last summer -- beset by problems at work, making call after call on his cellphone -- he forgot to drop his son, Chase, at day care. The toddler slowly sweltered to death, strapped into a car seat for nearly nine hours in an office parking lot in Herndon in the blistering heat of July.

It was an inexplicable, inexcusable mistake, but was it a crime? That was the question for a judge to decide.
