JACKSON, MICHIGAN (WTVB) - That Michigan woman who continued to live with her boyfriend for two years after he died could be facing multiple charges after authorities discovered her NASCAR-watching buddy.  Linda Chase says she didn't want to be alone after her friend Charles Zigler died in his sleep around Christmas 2010, so she decided to prop his body up in his favorite chair so they could keep watching TV together.  Police discovered the body earlier this month after Zigler's family called to say they hadn't heard from him in a while.  A medical examiner determined he died of natural causes, but Chase -- who also admitted to cashing Zigler's Social Security checks after his death -- is still under investigation.  So far she has fully cooperated with police, and is the first to admit that she'll probably end up behind bars.  At 72, any sentence could be a life sentence.
