 Kirk Sigler, NPR News, Las Vegas, New Mexico. A man accused of a mass shooting in suburban Chicago nearly two years ago has rejected a proposed plea deal. Prosecutors in Illinois had said they had reached the agreement with Robert Cremo. He is accused of opening fire at a Fourth of July parade, killing seven people and wounding dozens of others. Instead, Cremo turned up in court yesterday and rejected the plea agreement. Leah Sondheim lost her mother in the attack.
