To satisfy personal need or desire

From an article about the suicide of Mark Linkous:

… paramedics found Linkous slumped against the foot of a pink door with the gun atop his body and the bullet casing a few feet away. Over a half-dozen Knoxville Police Department officers roped off the alley with yellow caution tape, questioned his friends, and later notified Teresa. According to his toxicology report, Linkous’ blood alcohol content was recorded at 0.43, over five times Tennessee’s legal driving limit. Benzodiazepines and antidepressants were detected in his system. The final police report simply described his motive: “To satisfy personal need or desire.”
