Investigators revealed that it took a day to find the body of a man after a Milwaukee garage fire. It happened near South 26th Street and West Greenfield Avenue on Jan. 3. According to documents obtained by WISN 12 News, workers clearing debris found 70-year-old Grant Forbes dead at the scene Jan. 4.Milwaukee Fire Chief Aaron Lipski explained that the building his firefighters responded to is split into three parts. The front portion is a storefront, and the two back portions are garage-type areas. Lipski said he believes the victim was living in the back garage for 15 to 20 years.Lipski described the building as having 'extreme hoarder conditions.'"The density and the compactness and the tightness of all of these different types of debris lead me to make the following conclusion that no reasonable person, no reasonable firefighter, no reasonable, experienced firefighter would anticipate that there would be a person inside of this densely packed of a pile of debris. Not in my 26 years of experience," said Milwaukee fire Chief Aaron Lipski. First responders were called to the scene three days in a row. The investigation report from the Milwaukee County Medical Examiner's Office details those visits. The first visit Milwaukee Fire Department made to the building that week was on Jan. 2, for reports of strong fumes coming from the building. Lipski said investigators determined the fumes may have been from a recently refinished floor within the building. The second visit was on Jan. 3 to put out several fires in the back portion of the building. The third visit was on Jan. 4, after workers clearing debris from the garage portions of the building discovered Forbes' body. "No reasonable person would anticipate that we would remove an entire junkyard worth of debris from a space believing somebody had created a fortress in the middle of it," Lipski said.Lipski said the body was in a three-foot-deep cement pit surrounded by household items and debris. "He was there at a moment of crisis. We know that people retreat back to what's comfortable in a moment of crisis. I would have to believe I mean, he was aware of that space and whatever tunnel he had created to get there," Lipski said.Lipski said the cause of the fire is undetermined. "You can see the cinder block in the pictures. It's not smoke-scarred. The individual had no evidence of burn injury," Lipski said.Forbes' cause of death, according to the medical examiner's office, is listed as an accident, pending toxicology results and further investigation. "This is an absolutely horrific situation and I don't want that lost and I don't want the fact that people have questions about this lost. I would have the exact same questions," Lipski said.
