Police are asking for the public’s help in locating an elderly man reported missing in the Chicago area early Thursday.

Charles Almond, 82, was last seen Wednesday night near East Garland Park on Chicago’s West Side. Witnesses say they saw the man near the intersection of Washington Boulevard and North California Avenue but were unable to provide details about where he was going.

Chicago police have not released details about who he may have been in contact with around the time of his disappearance.

Almond is considered a “high risk” person due to his personal medical needs. Investigators told reporters Almond was previously diagnosed with dementia and may require medical assistance in dealing with his condition. This makes Almond a potential risk to both himself and those around him without the correct treatment.

Mayo Clinic defines dementia as a neurological disorder that commonly affects the elderly and most commonly occurs from Alzheimer’s disease. Symptoms of dementia include memory problems, confusion, poor concentration, changes in one’s personality and behavior, apathy, withdrawal, depression, agitation and hallucinations. Certain symptoms can be treated if one is diagnosed early enough and is provided proper treatment.

Almond is described as an African American male, standing 5-foot-8, weighing 120 pounds, with grey hair and brown eyes. He was last seen wearing blue jeans, white sneakers and a long-sleeve red shirt.

Investigators are urging anyone with information that could help locate him to come forward.
