It's been more than seven months since a Wauwatosa man was killed at Wisconsin's most popular state park.
Sauk County investigators are hopeful they are close to finding John Schmutzer's killer.
Schmutzer's body was found in October along a trail in Devils Lake State Park, after what was believed to be a random attack.
Detectives have developed a "person of interest" observed running near the scene.
Witnesses told detectives that the person of interest was about six feet tall, slender to average build, with darker-colored pants with ripped out knees, and a dark-colored top, possibly a hoodie. The clothing was described as “not standard running apparel," according to the office.
"We have at least 15 witnesses that saw this person," said Sauk County Detective Lt. Christopher Zunker. "Dark clothing, mask, potential hoodie or hat, ripped out black pants of some sort... scared or uneasy."
The office said during a Nov. 11 press briefing that the suspect may be acting unusual, nervous, and displaying emotions and habits of someone dealing with the trauma of killing another person.
