Several computers and alcoholic beverages were left untouched, according to the report.
"The suspect/s were there to collect specific items but attempted to make it look like a random burglary," according to the report.
The police description of the incident with names blacked out was obtained by The Associated Press through a public records request.
The state Democratic Party is waiting for police to finish their work, said spokesman Benton Strong.
"It's premature to make any guesses what or why it happened," he said Wednesday. "We know offices were broken into and a lot of things were stolen."
"I have no idea if there's more to it," he said.
Inslee spokeswoman Jaime Smith said her laptop was among the stolen items, but she wouldn't speculate on a motive.
