Rebecca Middleton's mother Cindy Bennett is sitting in Greg's Steakhouse, just across the road from the Supreme Court, sipping orange tea. Marsha Jones, the mother of Shaundae Jones, murdered four years ago this month, is here, too.

Their thoughts are with the families of the 33 students shot dead at Virginia Tech on Monday morning, the worst gun massacre in U.S. history.

Sat in this corner restaurant, away from the TV cameras, Mrs. Bennett talks frankly and with hope that the court hearing she travelled from Canada to attend will finally persuade the authorities to take a fresh look at the circumstances surrounding her daughter's death - and the flawed investigation that followed - with a view to pressing fresh charges.
