MEXICO CITY — Top Mexican drug lord Joaquin "El Chapo" Guzman has dropped off Forbes magazine's billionaires' list after four years on it.
Guzman first made the list in 2009 with a fortune listed at about $1 billion and stayed on it through 2012.
Guzman heads the Sinaloa cartel, Mexico's most powerful international drug trafficking network, and has been in hiding since escaping from a Mexican prison in a laundry cart in 2001.
Forbes senior wealth editor Luisa Kroll said in a statement that the decision to drop Guzman was based on suspicions that "an increasing chunk of money is going to protect him and his family."
Guzman's family has grown; the Los Angeles Times reported in 2011 that Guzman's wife, former beauty queen Emma Coronel, gave birth to twin girls at a U.S. hospital. Pressure from authorities and rival cartels has also stepped up.
"As the leader of the Sinaloa cartel, he is one of the most powerful people in the world, but no longer someone we are confident enough to call a billionaire," according to the statement.
Kroll noted that Guzman's whereabouts are unknown, and he could not be reached to verify figures on his wealth.
Guzman is believed to spend much of his time in a rural, mountainous area of northwestern Mexico, but reports of him have surfaced as far afield as Central America.
Mexican telecom magnate Carlos Slim continues to head the list, with a fortune estimated at $73 billion.

Donald Trump's Video Gaffe
Days before the presidential election, <a href="http://www.forbes.com/profile/donald-trump/">Donald Trump</a> set eyeballs rolling the world over by posting a <a href="http://www.youtube.com/watch?v=MgOq9pBkY0I&feature=youtu.be&hd=1">YouTube video</a> making President Obama an offer he wouldn't be able to refuse, to use a cliche not far removed <a href="https://www.facebook.com/photo.php?pid=26987232&l=9c7529f686&id=153080620724">from the real estate mogul’s own words</a>. The billionaire <a href="http://www.politico.com/blogs/burns-haberman/2012/05/trump-obama-born-in-kenya-124569.html">birther</a> gave the President a week to produce his college records and passport applications in return for a $5 million donation to the charity of Obama’s choice. His move derided in the press as, at best, a ploy for attention -- and needless to say,the President didn't bite. At the time, Trump told Forbes he'd had positive feedback from the video. <a href="http://www.forbes.com/pictures/mlf45jfkj/thor-batista/">Read more at Forbes</a>.
Silvio Berlusconi: Scandal As Usual
He remains on trial for alleged sex with an underage prostitute. He was sentenced to a year in jail in October for tax fraud. Yet Italian media billionaire and former prime minister Silvio Berlusconi was still toying with the idea of running for re-election as of a few weeks ago. <a href="http://www.telegraph.co.uk/news/worldnews/silvio-berlusconi/9748985/Silvio-Berlusconi-announces-engagement-to-27-year-old.html">He also introduced the media to his 27-year-old fiance in December</a>. He's 76, and still married to his second wife. Just another year in the life of the Bunga Bunga king. <a href="http://www.forbes.com/pictures/mlf45jfkj/thor-batista/">Read more at Forbes</a>.
Koch brothers' "Partisan" Pandering?
America's richest brothers Charles and David (pictured) Koch are rarely out of the headlines, but <a href="http://www.forbes.com/sites/clareoconnor/2012/10/15/koch-brothers-pro-romney-letter-to-staff-is-koch-pac-non-partisan-as-they-claim/">October's accusations were more serious</a> than the usual implications of secret electioneering. Shortly before the presidential election, liberal political magazine In These Times <a href="http://inthesetimes.com/article/14017/koch_industries_sends_45000_employees_pro_romney_mailing">obtained and published a packet</a> of voting information sent to 45,000 employees of Koch Industries paper subsidiary Georgia-Pacific. The materials included a list of Koch-endorsed candidates — those who “have received support from a Koch company or Koch PAC”, the company’s political action committee. For Oregon staffers, that list was comprised solely of Republicans: 14 of them at state level, plus the Romney/Ryan presidential ticket. Koch Industries denied any partisanship, but <a href="http://www.forbes.com/sites/clareoconnor/2012/10/15/koch-brothers-pro-romney-letter-to-staff-is-koch-pac-non-partisan-as-they-claim/">said the company supported "market-based policies and economic freedom."</a> <a href="http://www.forbes.com/pictures/mlf45jfkj/thor-batista/">Read more at Forbes</a>.

Rausing Family Tragedy
This year's most bizarre billionaire story is also the saddest. In July, Hans Kristian Rausing, 49-year-old <a href="http://www.forbes.com/profile/hans-rausing/">scion of a Swedish milk carton fortune</a>, was arrested on suspicion of drug possession in South London. Police then searched his five-story mansion in the city’s pricey Cadogan Place and<a href="http://www.forbes.com/sites/clareoconnor/2012/07/10/drug-addict-billionaire-packaging-heir-arrested-as-socialite-wife-found-dead/"> found the body of his American-born wife Eva</a>. The couple had struggled with addiction for years; Eva had once been arrested trying to smuggle heroin and crack into a party at London's US Embassy. It emerged during police investigations that Hans had been living alongside Eva's corpse for some weeks. He was <a href="http://www.forbes.com/sites/clareoconnor/2012/07/18/billionaire-hans-kristian-rausing-charged-with-preventing-burial-after-living-with-wifes-dead-body-eva-rausing-kemeny-tetra-pak/">charged with "preventing the lawful and decent burial" of his late wife</a>, who was subsequently found to have died of a cocaine overdose. <a href="http://www.forbes.com/pictures/mlf45jfkj/thor-batista/">Read more at Forbes</a>.
Pinault's Baby Mama Drama
French fashion tycoon Francois-Henri Pinault comes from a family worth some $13 billion. His great wealth was at the crux of <a href="http://www.forbes.com/sites/clareoconnor/2012/05/03/billionaire-baby-daddy-drama-linda-evangelista-takes-fashion-mogul-francois-pinault-to-court/">a nasty court case involving his one-time girlfriend, supermodel Linda Evangelista</a>, who claimed the billionaire heir hadn't paid a cent (or euro, as the case may be) in child support for the son he fathered five years earlier. Since then, Pinault has married another beauty, actress Salma Hayek (pictured with the Gucci mogul). Pinault implied in court that he thought Evangelista may have gotten pregnant on purpose during their brief relationship. Lawyers for the cover girl countered that he'd lavished money and attention on his child with Hayek while ignoring his son Augie. The couple settled for an undisclosed amount in May. <a href="http://www.forbes.com/pictures/mlf45jfkj/thor-batista/">Read more at Forbes</a>.
