An Arizona jury has refused to award damages against former Maricopa County Sheriff Joe Arpaio at a civil trial for bringing a since-dismissed criminal case against one of Sen. Jeff Flake's sons in the heat-exhaustion deaths of 21 dogs. Jurors deliberated nearly an hour before ruling late Thursday against Austin Flake and his then-wife Logan Brown in their malicious-prosecution lawsuit stemming from Arpaio's investigation into the heat-exhaustion deaths of 21 dogs at a kennel operated by Flake's in-laws. Flake and Brown, who were in college at the time, were caring for the dogs while the in-laws were out of town.
