GALT -- A police officer in the Sacramento County city of Galt was shot and killed Tuesday after responding to a report of a burglary, authorities said.

K-9 officer Kevin Tonn, 31, was one of two officers who responded to a burglary in progress on the 200 block of F Street in Galt around 11:30 a.m., according to Galt police Lt. Jim Uptegrove.

While officers were interviewing neighbors, one of the witnesses pointed down the road to some train tracks, roughly a block away, identifying the burglary suspect.

Tonn attempted to approach the man, but Uptegrove said the man became aggressive and an altercation between Tonn and the suspect ensued.
