time. Citus, a police dog, accompanied Peterson in the patrol car.
According to Peterson, he observed Dennen behave curiously as Peterson drove by. Dennen carried a suspicious, but unknown object — possibly a white plastic bag. Peterson noticed that Dennen repeatedly glanced at him in a nervous fashion, and then moved his hand in order to conceal the object he carried. Suspicious, Peterson turned his vehicle around to get a closer look. Immediately, Dennen sprinted to the intersection of 13th Avenue East and East Fourth Street and then headed east. Peterson completed his U-turn and followed. However, when Peterson arrived at the intersection, Dennen had disappeared.
Peterson surveyed the area and surmised that Dennen must have returned south through the backyards of the homes on 13th Avenue East. At exactly 2:36:48 a.m. Peterson radioed the situation to the station, stopped his car, and decided to investigate. Peterson went on foot and brought Citus with him — as Peterson put it — for his own protection: “it was dark, the backyard areas were unfamiliar,” and he was in an area known for some criminal activity. Moreover, he “was unsure of who the individual was, and what, if anything he was carrying.” Because he was not tracking or apprehending Dennen, Peterson did not put Citus on a leash nor give him any commands.3
Peterson and Citus began to look for Dennen. After a few moments, Citus stopped and indicated that he had picked up a human scent from an unexpected direction — away from the houses and toward a wooded area. Citus and Peterson changed course to follow this scent. As they were running, Citus ran some distance ahead of Peterson — approximately fifteen-to-thirty feet. However, as soon as Citus entered the wooded area, Peterson commanded him to return. Citus slowed his pace, and then returned to Peterson. Upon Citus’s return, Peterson leashed him.
At this point, Peterson and Citus were standing about fifteen-to-twenty feet from the edge of the woodpd area. Peterson then heard movement from that area. He identified himself, announced Citus’s presence, and ordered whomever was hiding in the woods to come out. Shortly after Peterson’s announcement, Peterson heard the sounds of breaking brush and a loud crash. Peterson and Citus entered the woods. After doing so, Peterson and Citus came to the edge of a deep, muddy, and steep ravine. They descended about fifteen feet and then saw Dennen lying face-down in a creek bed, which was an additional thirty-five feet below them.
At 02:38:06 a.m. Peterson radioed the dispatcher and requested medical assistance. Tanksi and Officer M. Peterson,4 the two officers who were at the party, left the house and headed toward the river. After descending into the ravine, they found Dennen seriously injured. The officers attempted to resuscitate Dennen. Dennen was rushed to the hospital for treatment. Unfortunately, Dennen had suffered a severe head injury and remained in a coma for several weeks.
Toxicology reports later revealed the presence of barbiturates, amphetamines, and an alcohol level of .227 in Dennen’s blood. Medical records reflected that

The City of Duluth has no policy regarding whether a dog must be on a leash when tracking a suspect. According to the testimony of several witnesses, if a canine is tracking a suspect, he will usually be on a leash.
