"It TMs really a shock for the community and for Michigan," said Kramer TMs neighbor Bob Miller.
Bob Miller is one of Kramer TMs neighbors.
He says Kramer may have died of a heart attack, and emergency crews tried to revive him for an hour.
"I know he had heart surgery and back surgery within the last month, month and a half; I think it was too much for his body," said Miller.
For the past 20 years he lived alone at this residence, neighbors say they came over quite often to check on Kramer, and to help out with household chores.
"Friends of ours and myself could tell that he just wasn't the same," said Timothy Hudson, Kramer TMs Neighbor.
Neighbors say Kramer talked about his two kids often, and after an illustrious athletic career, considered his children his greatest accomplishment.
"I know that his son was out here, and Tim says last week he went out to dinner with him, so I am glad they had that time together, and his sister was with him when he passed," said Miller.
Timothy Hudson was Kramer TMs close friend for 20 years, he says Kramer was philosophical and learned life lessons from him.
"Don TMt sweat the small stuff, you probably won't remember it tomorrow anyway," said Hudson.
Hudson is even mentioned in Kramer TMs book called, That TMs Just Kramer.
"As much as I got out of him being my friend, it TMs going to have an affect on my life not having him around anymore," said Hudson.
What will remain is number 87.
