At 10 p.m . ET Sunday , police officers responded to a report of gunfire at the home in West Bloomfield Township , Michigan , according to a police spokesman .

It appeared that the 50-year-old was on the verge of losing almost everything . According to court documents , Coley was scheduled to have an early intervention conference on Monday morning in his recent divorce case , a day on which he was reportedly about to be evicted . In her filing , Coley 's ex-wife , Deniece , alleged he attacked her on June 12 and she moved out of the house . Deniece Coley said her husband had cheated on her and subjected her to `` physical , mental , emotional and psychological abuse . '' The divorce was granted six days ago , according to CNN affiliate WDIV . The Coleys were married in November 1998 and have a 7-year-old child .

He was also the subject of a federal lawsuit surrounding an auto carrier company that his financial holdings company owned until it closed its doors in January 2010 . The complaint alleges that Translogic Auto withheld more than $ 9,600 from employees ' paychecks that were intended for an insurance plan . The insurance company canceled employees ' policies , due to nonpayment of premiums , the suit says , and employees and beneficiaries lost benefits . The suit also says Coley transferred more than $ 341,000 to himself or affiliates during the time when the company failed to pay insurance premiums . Coley was the sole defendant in the lawsuit , filed by the U.S. Department of Labor . WXYZ reported he was also found in default to two banks for $ 52,000 in one case and $ 43,000 in another .

Ford spokeswoman Kelli Felker did n't confirm what role Coley filled at Ford . He also worked at General Motors and UPS , according to the LinkedIn page . A resume that was last updated in June 2011 on the website Indeed.com mirrored the LinkedIn profile . Deniece Coley said in her divorce petition that her then-husband had n't worked in three years .
