Anna and Andrij Jakymec were awoken by about two dozen armed officers just after midnight early Friday morning when the officers, acting on a tip from an informant, raided their home in search of drugs and weapons.
According to the Chicago Tribune, Steve Patterson, a spokesman for the sheriff's department, said officers relied on an informant who had provided credible information in other investigations. Based on the tip, officers obtained a search warrant on Thursday.
Officers searching for a drug offender broke into the couple's home, shattering glass and breaking down the door. It turns out they had the wrong house. All of the officers found was the frightened elderly couple.
The couple's son Andrew said they were terrified because they thought it was a home invasion, the Chicago Tribune is reporting.
"I think the most potent drug they have is aspirin," he told the paper.
