PERU, Ind. (AP) — State police say at least 25 rounds were fired in about 20 seconds during the shootout that led to the death of a central Indiana sheriff’s deputy.

Investigation results released Thursday said Deputy Carl Koontz and Sgt. Jordan Buckley of the Howard County Sheriff’s Department fired 16 rounds in the March 20 shootout inside a Russiaville mobile home but none struck 25-year-old suspect Evan Dorsey because he was hiding behind a furnace.

It says Dorsey fired about nine shots from two handguns, striking each of the officers, before fatally shooting himself.

Prosecutors say the home was a drug-trafficking hub, and they filed drug charges Wednesday against six people and charged three others with misdemeanor visiting a common nuisance. Three of the six facing drug charges remained at large Thursday.
