After reaching TV superstardom playing Arnold Jackson on "Diff'rent Strokes" in the late 1970s and early 1980s, Coleman's life after the show included years of financial, legal and health troubles, including a congenital kidney condition, leading up to his death.
Coleman and Price married on a Nevada mountaintop in 2007 after meeting on the set of a 2006 film called "Church Ball." She was 22, he was 40. Shortly after they sat down with "Inside Edition," and it looked like the honeymoon was already over.
"We are not real showy love people," Coleman said. "We do all that at home."
"He is not romantic, but I'm kind of different," Shannon said.
"Gary and Shannon did have a very tumultuous relationship," People.com's Fleeman said.
One of Coleman's final public appearances was in May 2008, when he and Price went on "Divorce Court" not to end their marriage, but to save it.
Price complained that she and Coleman had ugly fights and that the actor threw temper tantrums "like a 5-year-old does." Coleman admitted to Judge Lynn Toler that he had a bad attitude, but that was because he hadn't had an easy life.
"I don't have any friends and don't have any intention of making any," he said, according to a transcript of the show. "People will stab you in the back, mistreat you, talk about me behind your back, steal from you. And they're not really your friends. They're only there because you're a celebrity or because they want to get something from you."
"We may go a week and not speak to each other," Coleman said. "I have very low self esteem. I don't feel very successful in life."
In 2009 Price was charged with domestic violence and disorderly conduct. This past January Coleman was taken in for a domestic violence warrant.
The year 2010 was particularly hard for Coleman.
In January, he was arrested for failing to appear in court after a domestic disturbance. His health has also faltered -- Coleman suffered seizures in January and again later February on the set of "The Insider."
Nine days later, in what is believed to be his final television appearance, Coleman lashed out at "The Insider" guest panelist Lisa Bloom when she asked if he ever lay hands on his wife.
"You go somewhere and drown yourself in the ocean!" Coleman shouted.
"Is that the way you talk to your wife?" responded Bloom.
"Yes, if I have to!" exclaimed Coleman. "If I need to, but I don't. I don't know about you, I don't care about you! If you get hit by a bus I am not going to care!"
In a radio interview last year Coleman reflected on his life, and the parents who he accused of stealing three quarters of his television earnings.
"I am still bitter about it," Coleman said. "It still hurts, it still hurts. You do midget mascots to pay the mortgage."
