A 93-year-old man froze to death inside his home, an autopsy has determined, just days after the city limited his flow of electricity for not paying his bills.

Marvin E. Schur died "a slow, painful death," said Kanu Virani, Oakland County's deputy chief medical examiner, who performed Schur's autopsy.

Neighbors discovered Schur's body on Jan. 17. The indoor temperature was below 32 degrees at the time, the neighbors told The Bay City Times for a story Monday.

Schur had no children, and his wife passed away several years ago.

The man had almost $1,100 in unpaid electric bills, said neighbor George Pauwels Jr., who discovered Schur's body.

The utility installed a "limiter" device outside Schur's home on Jan. 13, said Bay City Manager Robert Belleman. The device limits electricity flow to the home and blows out like a fuse if more than allowed is drained. Belleman said he doesn't know if anyone talked to Schur to explain how to reset the device to restore power.
