LINCOLN, Neb. (AP) — The president of the Capital Humane Society said staff failed to tell owners their adopted dog, who was fatally shot by Lincoln police, was conditioned to not like law enforcement.

Max, a black-and-white mixed breed dog, charged at and jumped onto the chest of Officer Jason Brownell, who shot the dog twice. The officer was visiting John and Lynette Markey Sunday about a minor traffic accident that occurred the day before.

According to the society president, Max’s former owner decided not to claim Max from the shelter. He informed the staff that Max had witnessed his encounters with law enforcement, and associated them with an unpleasant atmosphere.

Downey says he is trying to find out why the Markeys were not informed of Max’s aversion to police. The couple says they will try to adopt another dog.
