A grand jury indicted a Bexar County sheriff's deputy for the deaths of two of the department's K-9's in July 2012.
Deputy Steve Benoy faces misdemeanor animal cruelty charges, and is accused of leaving the dogs locked in their kennels in the back of a hot patrol unit.
Benoy left town for the night, then realized he had left the dogs in the patrol unit the next day. He returned and discovered the dogs had died of heat exhaustion, BCSO officials said.
If convicted, Benoy faces up to a year in jail and a fine of up to $4,000. Benoy was placed on administrative duty after the incident pending the results of an internal investigation.
