A suspected gunman took a plunge into a cold koi fish pond but couldn’t hide his smell from the police dog that tracked him to his backyard hiding spot Sunday, police said.

Before being carted off, Aaron P. Williams, 23, of Spokane, was checked for hypothermia. He was booked into the Spokane County Jail on a charge of first-degree assault with a firearm, police said.

The arrest followed a shooting just before 2 a.m. in the parking lot of the nearby Goodtymes Pub, 9214 E. Mission Ave., during a confrontation between two groups of men.

One man suffered a non-life-threatening gunshot wound to the leg, police said.

The alleged shooter ran south from the pub and was tracked by the Spokane Valley police dog to a home in the 9300 block of East Sinto Avenue.

A small, semi-automatic handgun that police believe was used in the shooting was found in a nearby mailbox.
