(AP) — Topeka police have released a report on the fatal shooting of two Topeka police officers killed last year during an armed standoff with a 22-year-old man.

The nine-page report released Tuesday includes a detailed timeline of the events leading up to the December 2012 fatal shootings of Cpl. David Gogian and officer Jeff Atherly. David Tiscareno was killed about 12 hours after he shot Gogian and Atherly as they investigated reported drug activity at a central Topeka grocery store.

While the report contains some new details, much of the information had been previously released.

The report is available on the front page of the department’s website until Dec. 3.
