"The sweetest people in the world and I just can't believe someone would do something like that if you're going to rob them then rob them but you don't have to kill them," says Yvonne Pacula.

The murders of Reynato (77) and Leticia Cardino (75) are especially tough on Yvonne Pacula and her family. Because to them, the Cardinos weren't just neighbors, but close friends they called Grandma and Grandpa.

"They had open arms, they would welcome anybody over," says Christine Pacula.

"They'd help the neighborhood out, whatever you wanted, they'd help you out," says Walter Pacula.

The elderly couple's son discovered their bodies at around seven p.m. Wednesday. He told police he caught an intruder inside, Who then assaulted him to the point of hospitalization and then ran away.

"His face was all bloody, all he did was call out my name and say call 911 we just got robbed," says Walter Pacula

Police aren't saying how the suspect got in or out of the home and if he got away with anything.

"Investigations of this magnitude you start really broad and you narrow in as the investigation progresses and investigations take time there's a lot too them and there's a likelihood that we may keep the scene for another 24 hours," says Deputy Chief Greg Lindmark.

Police called in representatives from the Illinois State Crime Lab and are interviewing neighbors for clues. As for the Pacula's, they say this peach tree will serve as a daily reminder for them. Since it was a gift from the Cardinos. A gift that has yet to bloom.

Winnebago County Coroner Sue Fiduccia says the couple died from blunt force trauma to their bodies.

Police say they're looking for a black man with an athletic built between 23 and 25 years old. He's six foot weighing about 175lbs.
