Robert Marlowe Amparan is an American criminal defense attorney based in San Francisco, California.
In August 2006, an American teacher living abroad named John Mark Karr falsely confessed to the unsolved murder of JonBenét Ramsey, creating a media frenzy.
Karr was arrested in Bangkok, Thailand, on August 16, 2006, by Thai authorities, then released to U.S. agents and flown first to Los Angeles, California, then to Boulder for further investigation.
On August 28, prosecutors announced they had decided not to pursue charges in connection with the murder after DNA tests failed to place Karr at the scene.
Karr was held in Boulder until September 12, 2006, when he was transported to Sonoma County, California to face unrelated misdemeanor child pornography charges.
