The Orange County District Attorney's Office had already prepared a criminal complaint against Dorner in connection to the Feb. 3 slayings of Monica Quan and Keith Lawrence in Irvine.
The office on Feb. 6 authorized the arrest of Dorner, but waited to file criminal charges until he was captured.
"This decision was reviewed and discussed daily and the OCDA was prepared to file a case against the defendant on a moment's notice should he have been apprehended or new developments in the case deemed it appropriate," prosecutors wrote in a press release.
Dorner's complaint included two counts of murder with special circumstance allegations of lying in wait and committing multiple murders.
Prosecutors said the District Attorney's office likely would have sought the death penalty.
Officials said their investigation is ongoing.
