The Winnebago County Coroner's Office has been working for most of the past year to identify decomposed human remains which were found in a garbage can outside an apartment building on Market Street in Rockford in July.

The coroner's office later determined it was a middle-aged Caucasian male. Tests indicate lower-spine degeneration, which means the man may have walked a lot.

The Winnebago County Coroner released the official cause of death for a former Northern Illinois University football player.  

Winnebago County Coroner Bill Hintz says Alex Kube died from cardiac arrhythmia, cardiomegaly and left ventricular hypertrophy. He says that means Kube’s heart stopped beating because his heart was enlarged due to a thickened left ventricle.

Hintz says Kube’s heart weighed more than 700 grams.

“To give you an example, you know, I’m 220 pounds at five foot, ten inches,” Hintz said. “My heart should weigh about 300 grams.”

A former Northern Illinois University football player who died last week at the age of 29 had an enlarged heart, but the actual cause of death has yet to be determined. 

Alex Kube was pronounced dead Wednesday night at Rockford Memorial Hospital.

Kube most recently was an assistant football coach at Rockford East High School. He had been a star linebacker for NIU and a football star at Cary-Grove High School, where he graduated in 2006.

Winnebago County Coroner Bill Hintz says an autopsy was performed Thursday.
