Murderabilia, also known as murderbilia, is a term identifying collectibles related to murders, murderers or other violent crimes, coined by Andy Kahan, director of the Houston Police Department's Crime Victims Office.
Buyers typically seek collectibles that are either artifacts used or owned by murderers and items (often artwork) created by them. According to crime writer Leigh Lundin, buyers may be interested in the macabre, but many believe such artifacts offer power and control.
Virtually anything once owned by mass murderers or serial killers can be marketed, such as vehicles, houses, and especially weapons used in crimes. Clothing is also in high demand, particularly clothes worn during crimes themselves.
Serial killer art
Killer art is defined as poetry or artwork created by mass murderers and serial killers while in prison. Often, this process is used as a therapy device, or for further understanding a particularly disturbed psyche, while in other instances it is purely a method of time spanning entertainment for imprisoned individuals. The artists vary dramatically in skill and themes covered.
John Wayne Gacy, Richard Ramirez, Glen Edward Rogers, and Henry Lee Lucas are a few of the better known American serial killer artists. Perry Smith, the mass murderer known from Truman Capote's famous work In Cold Blood, was also a prolific artist.
In May 2001, eBay banned the sale of murderabilia items, forcing the industry underground. One of the more prominent dealers of murderabilia who sold on eBay  launched their own web site, Supernaught, the first of its kind dedicated to selling true crime collectibles.  
In 2005, a serial killer's artwork was sold online in Massachusetts. State lawmakers proposed to block the activity, setting off a debate on free speech rights of prisoners. In 2007, American school shooter Wayne Lo caused controversy after it was found that he was selling his artwork on a web site.
In 2010 Sen. John Cornyn, R-TX, and Sen. Amy Klobuchar, DFL-MN, teamed up to introduce a bill in Congress that would outlaw what supporters view as a disgusting industry. The bill is called the "Stop the Sale of Murderabilia to Protect the Dignity of Crime Victims Act of 2010," and comes after several individual fights over the issue.
Eric Gein, whose murderabilia web site Serial killers ink is often in the news for selling items belonging to serial killers, is an outspoken opponent of the bill, has enlisted the help of the ACLU and claims the bill is an anti-civil liberties bill.
In June 2011, the United States Government auctioned off personal items which belonged to Ted Kaczynski which were found in his Montana cabin upon his capture in 1996. The auction took place entirely online. The proceeds went to victims and victims' families of Kaczynski's crimes.
