Death of David Coughlin

David Coughlin was killed in 1999 in the desert of southern New Mexico, in the United States, after he and Raffi Kodikian got lost while hiking. Kodikian later pleaded guilty to second-degree murder, saying that it had been a mercy killing, and served 16 months. He was released in November 2001.

Kodikian and Coughlin, best friends since college, were in their twenties and lived in Boston, Massachusetts. Kodikian was an aspiring journalist and Coughlin was a traffic policy analyst. In July 1999, the two set off on a road trip from Boston to California, where Coughlin planned to attend graduate school. On August 4, they arrived at Rattlesnake Canyon in Carlsbad Caverns National Park and made camp.

After days of hiking, the two became lost and dehydrated. Kodikian and Coughlin had only brought three pints (1.42 liter) of water and one pint (0.47 liter) of Gatorade. One pint of water was used to boil hot dogs during their first evening in the canyon. Although they had a topographical map, neither knew how to properly read it. The two took extreme measures, including licking rocks, eating cactus fruit, even drinking their own urine. Kodikian abandoned the idea of drinking his own urine after gagging.

The third night, Coughlin began vomiting, according to Kodikian. On August 8, Kodikian wrote in his journal:

I killed & burried [sic] my best friend today. Dave had been in pain all night. At around 5 or 6, he turned to me and begged that I put my knife through his chest. I did, and a second time when he wouldn't die.

Lance Mattson, a park ranger who had been searching for the campers, discovered Kodikian badly dehydrated. When the ranger inquired about Coughlin, Kodikian pointed to a pile of rocks and replied, "I killed him."

Kodikian's attorney, Gary Mitchell, described the killing as an act of kindness. He further stated that it was part of a death pact between the friends and Kodikian intended to kill himself too, but was too weak to do so. Eddy County sheriff Michael A. Click stated that Kodikian was "moderately to severely dehydrated", and was not close to dying when Mattson found him. Authorities further noted that Kodikian had buried Coughlin's body under rocks, some weighing more than 70 pounds (32 kg). The weight of the rocks and the completion of the task seemed remarkable for someone seriously dehydrated. The autopsy on Coughlin revealed that while he was dehydrated, it did not appear to be fatal.
