Chuck and Robin Nordell were at home with their two children last October when officers on a drug investigation burst into their house. The officers had the wrong address.
The Nordells live just a few doors down from the house where the officers were supposed to search.
After the raid, the family learned that the officers waited several days to report what happened, Robin Nordell said.
"I am here to apologize to the Nordell family on behalf of the police department," said Capt. Kevin Hamilton, Fullerton's acting police chief.
Hamilton said the last time Fullerton officers raided the wrong place was in the early 1980s. He said an internal affairs investigation into this incident is nearly complete.
