(STMW) — Authorities are asking the public’s help in finding a distraught Chicago man who was last seen in a southwest suburban forest preserve.

John Michael Cunningham, 27, was last seen “in a fit of work-related frustration” about 10:45 a.m. Thursday in a forest preserve area near 104th Avenue and McCarthy Road in Palos Park, according to Palos Park police.

Cunningham, who lives in the North Side Lake View neighborhood, was visiting his parents’ home when he went missing and has been dealing with some personal issues, police said.

“He was definitely frustrated when he left,” according to a statement from police.

Cunningham is described as 5-foot-10 and 160 pounds. He was wearing a gray T-shirt and black sweatpants and did not take his wallet or cell phone with him, police said.

The Cook County Sheriff’s office is leading a ground and air search.

Police are asking residents to check their garages, storage sheds, RVS, etc. for any sign of Cunningham. Runners and dog walkers on forest preserve trails are also asked to keep an eye out for him.

Anybody with information about Cunningham’s whereabouts should call sheriff’s police at (708) 865-4896 or 911.
