Jonathan Paul Luna (October 21, 1965 – December 4, 2003) was an American lawyer found dead under mysterious circumstances in Lancaster County, Pennsylvania while serving as an Assistant United States Attorney in Baltimore, Maryland. Luna had been stabbed 36 times with his own pocketknife and then drowned in a creek next to his car in rural Lancaster County. Investigations have proven inconclusive, and there is debate on whether Luna's death was murder or suicide.
