Across the nation

CHICAGO - A woman and two men were charged Sunday with stabbing a couple to death and taking their two children so she could pass off the baby girl as her own.

Adriana Mejia, 22, persuaded a cousin Arturo Leon and an acquaintance Gabriel Solache to help her kill factory worker Mariano Soto and his wife, Jacinita, early March 28, police said.

Police say the motive was to steal the couple's 2-month-old baby, Guadalupe Marie, whom Mejia had spotted with her mother at a Chicago health clinic one day earlier.

The discovery of the bodies sparked a widespread manhunt for the killers and the missing children. Police retrieved the children Friday when the accused woman's husband took the boy to police.

Police dressed in riot gear fired rubber and wooden projectiles into the crowd when people started throwing bottles, chunks of pavement and coins.
