In a Houston courtroom Monday morning, some of the relatives of the 19 illegal immigrants who died in a botched smuggling operation sobbed when they were shown photographs of the dead.

Former trucker Tyrone Williams faces a possible death sentence for leaving more than 70 people in the over-heated trailer of his truck in 2003.

Bringing the relatives into the courtroom was something his lawyers strongly discouraged - but Williams insisted they appear in person.
